The AD8123ACPZ is a triple, high speed, Differential Receiver and Equalizer. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry inside the AD8123 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 long cable equalization (up to 300m). Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.
