  • ADM6993F/FXFiber to Fast Ethernet Converter (TS1000 CPE complied) The ADM6993F/FX is a single chip

    ADM6993F/FXFiber to Fast Ethernet Converter (TS1000 CPE complied) The ADM6993F/FX is a single chip integrating two 10/100 Mbps MDIX TX/FX transceivers, a three-port 10/100M Ethernet L2 switch controller, and one OAM engine to meet demanding applications, including Fiber-to-Ethernet media converters, especially the fiber to the home (FTTH) media converters. The ADM6993F/FX feature set includes link pass through (LPT), TS1000 OAM frame receiving/processing/transmitting, programmable link status LED display, various loop-back modes, and one configurable MII ports for snooping/inserting OAM frame from/to 100Fx. The ADM6993FX is the environmentally friendly “green” package version.

  • UHF讀寫器設(shè)計中的FM0解碼技術(shù)

       針對UHF讀寫器設(shè)計中，在符合EPC Gen2標(biāo)準(zhǔn)的情況下，對標(biāo)簽返回的高速數(shù)據(jù)進(jìn)行正確解碼以達(dá)到正確讀取標(biāo)簽的要求，提出了一種新的在ARM平臺下采用邊沿捕獲統(tǒng)計定時器數(shù)判斷數(shù)據(jù)的方法，并對FM0編碼進(jìn)行解碼。與傳統(tǒng)的使用定時器定時采樣高低電平的FM0解碼方法相比，該解碼方法可以減少定時器定時誤差累積的影響；可以將捕獲定時器數(shù)中斷與數(shù)據(jù)判斷解碼相對分隔開，使得中斷對解碼影響很小，實現(xiàn)捕獲與解碼的同步。通過實驗表明，這種方法提高了解碼的效率，在160 Kb/s的接收速度下，讀取一張標(biāo)簽的時間約為30次/s。 Abstract:  Aiming at the requirement of receiving correctly decoded data from the tag under high-speed communication which complied with EPC Gen2 standard in the design of UHF interrogator， the article introduced a new technology for FM0 decoding which counted the timer counter to judge data by using the edge interval of signal capture based on the ARM7 platform. Compared with the traditional FM0 decoding method which used the timer timed to sample the high and low level， the method could reduce the accumulation of timing error and could relatively separate capture timer interrupt and the data judgment for decoding， so that the disruption effect on the decoding was small and realizd synchronization of capture and decoding. Testing result shows that the method improves the efficiency of decoding， at 160 Kb/s receiving speed， the time of the interrogator to read a tag is about 30 times/s.
