The male YangJiaGong peng the Rui source: product catalogs

 

Abstract: this paper introduces the AD the company USES the advanced direct digital frequency synthesis (DDS) technology launch of the high level of integration of the ad9850 frequency synthesizer work principle, main characteristics and the McS51 monolithic integrated circuit taking the interface, and give the interface diagram and part of the source program.

 

 

 

 

 

Keywords: direct digital frequency synthesis (DDS)

 

Control word sequence control ad9850 interface

 

1 ad9850 profile

 

With the rapid development of digital technology, a digital control method from a reference frequency source of frequency produce many technology, namely direct digital frequency synthesis (DDS) technology as a new force. The AD out high level of integration is the ad9850 frequency synthesizer in the typical product of DDS technology.

 

The first ad9850 to locust cmos technology, and its power consumption in 3.3 v power supply only for 155 mw when, expanding industrial temperature range-40 to 80 ℃ for, the 28 feet ssop package form surface. The ad9850 pins are shown as shown in figure 1, figure 2 for its component diagram. Figure 2 middle dash-dotted frame is a complete programmable DDS system, outer dash-dotted frame contains the main components of the ad9850.

 

Ad9850 containing programmable DDS systems and speed is used, can realize the digital programming the control of frequency synthesis. Programmable DDS the core of the system is phase accumulators, it consists of a adder and a n a phase of registers, n general for 24 and 32. Each to an external reference clock, phase registers and step length DiJia m. The output of the phase to phase registers control word after adding input to address lookup sine. Sine lookup contains a sine wave amplitude information the number of cycles, each address 0 ° in the corresponding sine ~ 360 ° range of a phase point. The input address lookup the phase information mapping sine wave amplitude signals, then drive dac to output model volume.

 

Phase register every 2 n/m a external reference clock to return to the initial state a, phase to every consumer goods a lookup sine cycle also returned to the initial position, so that the entire DDS system output a sine wave. The output of sine wave to cycle = tc2n/m, frequency fout = MFC / 2 n, tc, fc respectively for the cycle and external reference clock frequency.

 

The ad9850 32-bit phase accumulators will signal input to a truncated into 14 sine enquiry form, the output of the truncated lookup again after a 10 input into the dac, dac to its output two complementary current. Dac full range output current through an external resistance rset adjustment, adjust the relation of iset = 32 (1.148 v/rset), the typical rset value is 3.9 k ω. Will the output of the dac by low pass filter from inside the ad9850 after the comparator can direct output a jitter small square wave. The system function as shown in figure 3 below.

 

Ad9850 connected to the precision clock in source and write frequency phase control between words after can produce a frequency and phase can be programmed to control simulation sine wave output, this can be directly used for frequency sine wave signal source or the internal high-speed comparator into square wave output. In the 125 MHZ clock, 32 bit frequency control word can make the ad9850 output frequency resolution of 0.0291 hz; And have five phase control bit, and allow the incremental 180 °, according to phase 90 °, 45 °, 22.5 °, 11.25 ° or the value of the combined adjustment.

 

2 the ad9850 control word and timing sequence

 

Ad9850 have 40 control word, 32 bit used for frequency control, five for phase control. One used for power supply dormancy (power

 

Down) control, 2 to choose the way to work. This 40 control word can be through the parallel or serial input to the way ad9850. Figure 4 is the control of the input control word parallel timing diagram, in parallel in the way, through the eight bus a0… D7 will data input to register, in repeat 5 times then in fq-ud up along the 40 from the input data to register in frequency/phase data registers (DDS update frequency and phase output), but at the same time, address pointer is reset to the first input registers. Then in w-CLK rise along the into 8 bits of data, and put the pointer to the next input box, the continuous 5 w-CLK after rising edge, w-CLK the edge of it no longer function, until the reset signal or fq-ud up along the address pointer is reset to the first registers. In serial input methods, w-CLK up to 25 feet along the lead a serial data move, when moving after 40, with a fq-ud pulse can update frequency and phase output. Figure 5 is the corresponding serial input control word of sequence control chart.

 

The ad9850 reset (reset) signal is high effective, and pulse width is not less than 5 reference clock cycle. Ad9850 reference clock frequency general is far higher than the single chip microcomputer clock frequency, therefore the ad9850 reset (reset) end with the reduction of single chip can be directly connected.

 

It is: to choose the method of working two control bit, whether parallel or serial had better write 00, parallel 10, when in and the 10, serial 01, 11 are factory test retained control word, no

DSP and serial AD73360A a/D converter interface design

Source: electronic technology application author: HeXueHui Sue out

 

 

Abstract: discusses the ti company’s digital signal processor tms320vc5402 of multimodal buffer serial ports and serial a/d converter ad73360 interface design, expounds the both hardware and software implementation interface.

 

Key words: the multichannel buffer serial tms320vc5402dsp ad73360 a/d converter with the continuous improvement of the signal processing requirements and DSP technology unceasing development, more and more engineering and technical personnel began using DSP for system design. The United States of tms320vc5402 ti company (hereinafter referred to as vc5402) DSP has a fast calculation speed, power consumption and the characteristics of the high ratio of small, has set up a file in the personal mobile communication, signal and information processing as well as the automatic control etc a wide range of applications. The chip provides more than two channels buffer serial interface (MCBSP) and external communication equipment. It and serial a/d converter in the composition of the signal acquisition and processing system has the hardware design simple, reliability good characteristic. This paper describes vc5402 and ad73360 interface design.

 

 

 

1 vc5402 McBspvc5402 of the MCBSP is a synchronous serial interface, support a variety of communication and spi agreement, this serial may, according to the different needs of designer configurations, use very flexible. Its main characteristics as follows: full-duplex serial communication; Continuous send and receive data flow function; Have external clock input or internal programmable clock two clock control mode; But independent programming the sending and receiving frame synchronization; Multi-channel data transmission (up to 128 channels); Optional data width: 8, 12, 16, 20, 24 or 32 bit; Used for data compression μ law and law of a compressed extension; Programmable clock and frame synchronization polarity.

 

 

MCBSP including 6 pins, respectively is serial data send signal dx, serial data receiving signal dr, send the clock signal CLKX, receiving the clock signal CLKR, send frame synchronization FSX signal and receive frame synchronization FSR signal. Because MCBSP with a programmable in sampling and frame synchronization generator, so serial ports receive, send the clock and frame synchronization can not only produced by internal signal, by external input.

 

 

The MCBSP vc5402 of 23 registers control, except for a few can’t visit by program outside, generally in data communication serial port before they initialization, part of the register is memory mapping register, must through the son of address way access. Want to visit the MCBSP these registers, first to register to be visited the son son address register spsa wrote the address, and then you can register on access to data.

 

 

MCBSP can transmit and receive data process as follows: in sending data, you are going to send data wrote DXR registers, if XSR register is empty (the last time that the data sent by the dx pin has sent out), it will DXR register of data is copied to the XSR registers; And then in the frame synchronization FSX and clock under the action of CLKX, will XSR register of data by displacement to the dx pin output. In data from DXR registers copied to the XSR, you will be the next to the data sent wrote DXR registers, thus ensure data sent for. The process of serial port receives data and send a basic similar, but the opposite direction and vc5402 of multi channel of the serial port of receiving took three buffer.

 

 

In vc5402 piece inside, CPU and MCBSP data transfer between the three kind of way way way  inquires, interruption and dma mode. Whenever a serial port receives a word (new receiving data is copied to the DRR  1  2  registers) or send word from DXR register to register XSR copy when will change a serial port control register 1 (spcr1) the rddy and serial interface control register 2 (spcr2) of the xrdy flag bit, so CPU can through continuous query method know whether the data sent and whether to receive new data, so as to determine the next step of operation. CPU can also receive through a serial port or send interruption, in an interrupt service routine is accomplished in the transmission of data, interrupted the trigger events can be selected, in processing must be set in advance before a serial port control register 1 (spcr1) and serial interface control register 2  spcr2 in corresponding place. The third way is by the number of the chip with serial connected dma, by a serial port synchronized events triggered finish data transmission dma.

 

 

MCBSP initialization mainly completes the serial port configuration, sending and receiving can set respectively, but to combine specific hardware design. The main job of a serial port initialization below  set FSR, FSX, CLKX and CLKR for input or output and their polarity; Single or double set is a phase frame synchronization; Set each frame contains data number; Set of data transmission word wide (for two phase frame synchronization, each phase of the corresponding word set wide for); Set the first frame synchronization of frame synchronization after whether be ignored; Set of data bits delay; Set of data sign extension method; Set the choice of transmission channel; If you use internal clock and frame synchronization generated signal, also need to clock and frame synchronization generator set in.

 

 

 

2 serial a/d converter ad73360ad73360 is AD out 6 channel analog input of 16 serial programmable a/d converter. Due to the same δ a/d conversion principle, has the good built-in aliasing resistance performance, so for simulation of the filter front end demand is not high, with first order rc low-pass filter can meet the requirements. Because of its sampling rate and input

Scanning China furniture industry is why eyeful is “foreign” brand

China is the world’s furniture production and export power, in 2006 China furniture exports more than Italy for the first time, as the world furniture exports first big country, in 2010 China furniture exports has amounted to $33.7 billion. And China’s import furniture line in successive years is ascension, China furniture association of data showing that, in the first half of 2011, China’s total import furniture nearly $1 billion, for two consecutive years of strong growth. Leonardo Da Vinci furniture to fake the place of origin, product quality problems such as qualified by CCTV after exposure, about the origin of the furniture of brand and consumption cause many discussions.

 

Scanning China furniture industry, we found that the Da Vinci household and false “foreign” brand of the island, it is just the chaos to China furniture industry the tip of the iceberg. Day price of furniture behind, with many of China’s domestic manufacturing of “foreign” brand, the most look not to understand the but again very explicit fashionable foreign names, only is domestic furniture with a layer of the skin “just.

 

Eyeful all is “foreign” brand

 

Literally go a large furniture stores, view most of the furniture store brand names are with the composition, have a plenty of Chinese pinyin QuanPin, some is the first letters of the alphabet of the abbreviations, if it weren’t for the next few Chinese followed, never expected to read. In addition to the name, the businessman in the promotion of the language or post poster are noble status. “Feel the Italian original design” “noble life from Europe,” “the British leisure classic”. The name of the brand furniture all claims to have more than half of Europe and America lineages, Italy, Britain, the United States, Germany and other countries.

 

Local brand furniture put on a layer of “foreign” skin, it’s easy to mistake for import furniture, plus the high prices, consumers in purchase are so seriously the sales staff “one-sided word”. Consumers in the gallery we see is has dismantled packaging, install good furniture, packing and packaging the label on the label, only after buy when receiving can see, this also virtually increased the risk of purchase.

 

In fact, the true and false furniture industry brand the mess has been on for a long time: the false mark, false conduct propaganda, gold-plated foreign brand, distribution chaos, authorized OEM label-attaching phenomenon also in furniture industry have already spread. The writer heard a dealer said, domestic under the banner of the import “export turns sale in domestic market” products can say now account for more than 95% of the import furniture, mostly in guangdong area by foundry production. For example, same a portfolio of sofa, and mark native brand, the price is in 8000 yuan; If the mark of Chinese and foreign and assets, the price is in 20000 yuan; If mark in the United States, and the price is up 7-80000 yuan, if is made in Italy are more expensive.

 

These so-called “foreign” brand furniture, says it is “import” the real wood furniture, pure wood furniture, pure solid wood furniture, many are in the big core board as the main raw material of the furniture that stick a skin. But, earlier this year zhejiang related departments market taken found, nominal “solid wood furniture” furniture detection rate is zero. Many manufacturers are dare to take all the world BuWei, damage the interests of consumers, mainly because of real wood under signs sell furniture that stick a skin, profit is multiplied, some profits can be as high as of hundreds, and the true of completely real wood furniture profit is not high, only 15% to 30%.

 

Why are “foreign” brand

 

True to the reason is that, in macalline Eurasian of the hippocampus, gold, such as household stores, real foreign furniture brand are not much, most furniture brand are derived from domestic, but these furniture brand but mostly play a “foreign” name, says raw materials from outside the wood, use of foreign advanced design, at first glance thought is imported brand, but its manufacturing sites in China.

 

So why are up a “foreign” name, called “foreign” brand? In order to cater to consumer tastes, in order to promote the brand quality and prestige, in order to achieve the purpose of increasing sales.

 

Now most of the furniture of consumer brand blindly accepted: first, the real foreign brand furniture does in product quality and after-sales service and so on more than the local brands to do well, especially some of the nations industrial level really in the leading international level, it is tempting to consumers.

 

Second, the local brands the lack of brand marketing strategy, in addition to price war every day, and not in the products and service level feet under strength, make consumers think local brands in the class is far and foreign brands. Third, consumers in China has always…… psychology, thought to have the “foreign” brand is the symbol of high quality life. In fact, consumers are not know, many “foreign” brand is not really “foreign”, but only on the surface of “foreign” : one is to stick a card production try to hold down costs, on the other hand, by creating international brand image to raise their profile cater to consumer, eventually get huge profits.

 

In Hong Kong, China or other countries or regions register a household company, only need thousands of yuan, whether foreign or joint venture form, has the qualification to purchase materials in foreign production, import proportion of women can choose any, and foreign can be said is pure entrance furniture. Many “high-end” and “foreign” furniture brand, go is this line.

 

In addition, some of the so-called “foreign” brand furniture, like the Chinese wood to a foreign names, confusion material name. Such as the domestic hua limu as Africa hua limu, let consumers feel quite advanced materials (to tell the truth, ShiHuo real consumers have no a few), in fact two entirely different materials. Some people through the hand knock, nose to smell and all the way, for those who coarsely useful, to the root of the fine work hard to discern. And those who can’t see the place but also use particieboard or density board, see the main body of the frame, is the real wood doors and drawer.

 

And, in furniture industry, many businesses that have to sell products to the very expensive to be normal, in fact, this is the order of the lack of competition furniture industry performance. For example, the current domestic furniture industry for after-sales maintenance term and category all does not have uniform standard, each brand after-sales service is uneven, in recent years in furniture industry in the list of complaints “glorious list”. This is also driven consumers trust “foreign” brand one of elements.

 

Who is really “foreign” brand

 

“Foreign” brand furniture there are many doorways, both fake “foreign” brand exist, it would be really “foreign” brand exist. Just in “the group of” really “foreign” brand less, false “foreign” brand, also mingled with a lot of half true half a fake “foreign” brand. But because most consumers lack of furniture knowledge, can’t understand what “foreign” brand is true, which is false.

 

The author in this definition here for a true and false “foreign” brand: the so-called really “foreign” brand, the foreign brand holder to business, or in domestic development his agent, goods directly by manufacturer; The so-called half true half a fake “foreign” brand, is the furniture manufacturers domestic money bought from abroad “foreign” authorized the use of the brand, and her production of furniture products had a “foreign” name; And those false “foreign” brand, two types: by domestic Chinese companies spend thousands of dollars to overseas registered trademark, furniture products in domestic production but, but with “foreign” brand identity in domestic sales; Another kind of false “foreign” brand is, domestic manufacturers abroad directly imitating the brand, to attack foreign brands patents and the consumers’ right to know the way there.

 

So, how do consumers to identify these true and false “foreign” brand?

 

The current China furniture industry was on the strategic messy period, industrial self-discipline level is low, the industry of the lack of regulation, the author cannot give consumers a accurate distinguish method. But the author can put in contact with “foreign” really brand experience sharing out. The author have been exposed to a Japanese furniture company and two American furniture enterprise, and to provide them with marketing consulting services have two years of time. In this period, the author found that several real “foreign” brand furniture practice and false “foreign” brand of the approach are worlds apart.

 

First of all, the real “foreign” brand furniture, is in the price is not “day price” the brand, also is not always a “expensive” brand, even is the price of their “low” even to consumers don’t believe they are really “foreign” brand.

 

Why is there such a phenomenon happens? Because these are really “foreign” brand of operator is not a native Chinese, they don’t understand China consumer buying habits (like cut price), so is marked prices (buy as much money as how many standard price), the results not only in competition lost to the Chinese counterparts, but also because no meet consumers cut price sense of achievement, but by the consumers as false “foreign” brand. So, those who never discount, don’t bargain, how much money will sell mark how much money “foreign” brand furniture, consumer is one of the conditions of the false and judgment;

 

Second, the real “foreign” brand furniture, on advertising rarely flaunt oneself is the “foreign” brand. Because they know that they are really the “foreign” descent, also worry that Chinese consumers in them as “foreigners”, worried about China’s consumers say they don’t understand Chinese demand and refused to buy, so, they always tried to publicity they are the needs of the consumers understand China, their products are based on Chinese human characteristics and life habits to design and production of furniture products. The real “foreign” brand furniture, its production factory some abroad, some at home, but they are more like stressed that they in order to adapt to the needs of the Chinese consumers, has set up factories in China, please consumer confidence their services. This and the fake “foreign” brand products of foreign manufacturing has emphasized the clearly different.

 

Furthermore, these true “foreign” brand in the domestic factory, and false “foreign” brand ban strangers into production workshop is different, its production process is transparent, workshop is open, visitors can be taken at will. Instead, false “foreign” the brand of the opening of the product exhibition hall, but become real “foreign” brand are heavily protected objects. If no invitation, and specialized personnel in the accompanying this under any stranger is unable to enter the true “foreign” brand furniture exhibition hall, and really the “foreign” brand furniture factory is banned in the exhibition hall at the pictures.

 

Finally, to give consumers a little advice: buy furniture is not a “foreign” brand is only. In fact, true and false “foreign” brand irrelevant, the key is better than the quality of the product. To buy in the written clear furniture sort, to specify the main ingredient and accessories, the name of the state of buying their own what kind of furniture, it is “completely real wood furniture”, “real wood cover furniture”, or “pure solid wood furniture,” best indicate the furniture price, colour and lustre and style. Buy for formal invoice, once found furniture not “solid” and ready to take out the evidence to maintain their own rights and interests.

 

Last word

 

Along with the enhancement of social informatization, the more information symmetry, the furniture of consumers increasingly rich knowledge, together with the fierce competition of the industry, also let many once depend on a lot of enterprise high loss of profit space, slowly returning to normal business activities.

 

In addition, with integration sales to reduce logistics cost, flat network sale system gets save link. And most at home to seek agent to the brand sales, compared to some international household brand in China market rooted steadily, will take to establish subsidiary company is one of the model, and at the same time through e-commerce platform, which can save countries, such as the general agent provincial middle link markups, let consumer get more direct benefits.

 

We have reason to believe that the scale of the global production, sales network and local globalization sales system simplification mode has be vividly portrayed, and sales system is simplified out the multilevel agent of complex link, whether domestic furniture, or imported furniture its price will gradually close to people change, mature standard Chinese furniture market is fast approaching. Those who have risked the interests of consumers, use industry loophole, and the law play outside knowingly breaks the law, carry out the production sales even the “dirty” manufacturer also will be eliminated and related to the market regulatory punishment.
