Part Details:

CAT-5 Receiver with Adjustable Line Equalization AD8128 FEATURES FUNCTIONAL BLOCK DIAGRAM Tuned to compensate for Category-5 (CAT-5) cable losses Up to 100 meters @ 120 MHz AD8128 HPF 2 voltage-controlled frequency response adjustment pins High frequency peaking adjustment Broadband gain adjustment VIN+ 2700 V/s slew rate VOUT VIN­ HPF Low output noise 1.5 mV rms integrated noise (1 GHz) @ 100 meters LPF equalized bandwidth 1-00 DC output offset adjust V V V 699 Low offset voltage error: 7 mV typ PEAK GAIN OFFSET 05 Figure 1. Equalized pass-band ripple ±1 dB to 70 MHz Input: differential or single ended Supply current: 24 mA on ±5 V Small 8-lead 3 mm × 3 mm LFCSP APPLICATIONS Keyboard-video-mouse (KVM) RGB video over unshielded twisted pair (UTP) cable receivers Professional video projection and distribution Security video GENERAL DESCRIPTION The AD8128 is a high speed, differential receiver/equalizer that Low integrated output noise and offset voltage adjust make the compensates for the transmission losses of unshielded twisted AD8128 an excellent choice for dc-coupled wideband RGB- pair (UTP) CAT-5 cables. Various frequency dependent gain over-CAT-5 applications. For systems where the UTP cable is stages are summed together to best approximate the inverse longer than 100 meters, two AD8128s can be cascaded to frequency response of CAT-5/CAT-5e cable. An equalized compensate for up to 200 meters of CAT-5/CAT-5e. bandwidth of 120 MHz can be achieved for 100 meters of cable. The AD8128 is available in a 3 mm × 3 mm 8-lead LFCSP and The AD8128 can be used as a standalone receiver/equalizer or is rated to operate over the extended temperature range of in conjunction with the AD8143, triple differential receiver, to -40°C to +85°C. provide a complete low cost solution for receiving RGB over UTP cable in such applications as KVM.
