The PI3EQX16621 is a low-power, high-performance 16Gbps
4-channel Mux ReDriver™.

The 4-Channel Mux ReDriver

The ReDriver provides programmable equalization, swing, and flat gain to optimize performance over a variety of physical mediums by reducing intersymbol interference. The ReDriver supports two 100Ω differential CML data I/Os between the
Protocol ASIC to a switch fabric, over cable, or to extend the signals across other distant data pathways on the user’s platform.

The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver. A low-level
input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. The channels’ input signal level determines whether the output is active.

The ReDriver also includes an adaptive power management feature to maximize battery life for power-sensitive consumer devices.
