AD8129ARMZ-REEL GENERAL DESCRIPTION

The AD8129/AD8130 are designed as receivers for thetransmission of high speed signals over twisted-pair cables towork with the AD8131 or AD8132 drivers. Either can be usedfor analog or digital video signals and for high speed datatransmission.1201101009080706050403010k100k1M10M100MFREQUENCY (Hz)CMRR (dB)02464-002Figure 2. AD8129 CMRR vs. FrequencyThe AD8129/AD8130 have excellent common-mode rejection(70 dB @ 10 MHz), allowing the use of low cost, unshieldedtwisted-pair cables without fear of corruption by external noisesources or crosstalk. The AD8129/AD8130 have a wide powersupply range from single +5 V to ±12 V, allowing wide common-mode and differential-mode voltage ranges while maintainingsignal integrity. The wide common-mode voltage range enablesthe driver-receiver pair to operate without isolation transformersin many systems where the ground potential difference betweendrive and receive locations is many volts. The AD8129/AD8130have considerable cost and performance improvements overop amps and other multiamplifier receiving solutions.RFVOUTVINRGVOUT = VIN [1+(RF/RG)]PD+VS–VS1845327602464-003Figure 3.
