GENERAL DESCRIPTION  
The AD8124 is a triple, high speed, differential receiver and  
equalizer that compensates for the transmission losses of UTP  
and coaxial cables up to 200 meters in length. Various gain stages  
are summed together to best approximate the inverse frequency  
response of the cable. Logic circuitry inside the AD8124 controls  
the gain functions of the individual stages so that the lowest  
noise can be achieved at short-to-medium cable lengths. This  
technique optimizes its performance for low noise, short-to-  
medium range applications, while at the same time provides  
the high gain bandwidth required for longer cable equalization  
(up to 200 meters). Each channel features a high impedance  
differential input that is ideal for interfacing directly with the cable.  
The AD8124 has three control pins for optimal cable  
compensation, as well as an output offset adjust pin. Two  
voltage-controlled pins are used to compensate for different  
cable lengths; the VPEAK pin controls the amount of high frequency  
peaking and the VGAIN pin adjusts the broadband flat gain, which  
compensates for the low frequency flat cable loss.  
For added flexibility, an optional pole adjustment pin, VPOLE  
allows movement of the pole locations, allowing for the  
compensation of different gauges and types of cable as well  
,
as variations between different cables and/or equalizers. The  
OFFSET pin allows the dc voltage at the output to be adjusted,  
V
adding flexibility for dc-coupled systems.  
The AD8124 is available in a 6 mm × 6 mm, 40-lead LFCSP  
and is rated to operate over the extended temperature range of  
−40°C to +85°C.
