Back to Signal Integrity - ReDrivers™/Repeaters/Signal Conditioners


1.8 V, 32 Gbps, 4 Channel 2:1 Mux/De-Mux Switch


The PI3EQX32904 is a low-power, high-performance 32Gbps 4-channel ReDriver™.

The 4-Channel ReDriver

The ReDriver provides programmable equalization, swing, and flat gain I2C Control, 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.
