AD8123
Overview
The AD8123 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable.
- 9 ns with 2 V step at 150 meters of UTP cable 8.0 ns with 2 V step at 300 meters of UTP cable 55 dB peak gain at 100 MHz Two frequency response gain adjustment pins High frequency peaking adjustment (VPEAK) Broadband flat gain adjustment (VGAIN) Pole location adjustment pin (VPOLE) Compensates for variations between cables Can be optimized for either UTP or coaxial cable DC output offset adjust (VOFFSET) Low output offset voltage: 24 mV Compensates both RGB and YPbPr Two on-chip comparators with hysteresis Can be used for common-mode sync extraction Available in 40-lead, 6 mm × 6 mm LFCSP
