The AD8128 is a high speed, differential receiver/equalizer thatcompensates for the transmission losses of unshielded twisted pair(UTP) CAT-5 cables. Various frequency dependent gain stagesare summed together to best approximate the inverse frequencyresponse of CAT-5/CAT-5e cable. An equalized bandwidth of120 MHz can be achieved for 100 meters of cable.
The AD8128 can be used as a standalone receiver/equalizer orin conjunction with the AD8143, triple differential receiver, toprovide a complete low cost solution for receiving RGB overUTP cable in such applications as KVM.
The AD8128 has three control pins for optimal CAT-5/CAT-5ecompensation. The equalized cable length is directly proportionalto the voltage applied to the VPEAK pin, which controls the amountof high frequency peaking. VGAIN adjusts the broadband gainfrom 0 dB to 3 dB, compensating for the resistive cable loss.VOFFSET allows the output to be shifted by ±2.5 V, addingflexibility for dc-coupled systems.
Low integrated output noise and offset voltage adjust make theAD8128 an excellent choice for dc-coupled wideband RGB-overCAT-5applications. For systems where the UTP cable is longerthan 100 meters, two AD8128 devices can be cascaded tocompensate for up to 200 meters of CAT-5/CAT-5e.
The AD8128 is available in a 3 mm × 3 mm 8-lead LFCSP andis rated to operate over the extended temperature range of−40°C to +85°C.
