Diodes Incorporated PI3EQX32914 32Gbps 4-Channel PCIe® 5.0 ReDriver™

Diodes Inc. PI3EQX32914 32Gbps 4-Channel PCIe® 5.0 ReDriver™ provides programmable equalization, flat gain I2C Control, swing linearity, and optimizes performance over a variety of physical mediums by reducing intersymbol interference. The ReDriver supports four 100Ω differential CML data I/Os between the protocol ASIC and 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 the signal integrity before the ReDriver. Each channel, which operates entirely independently, has an output squelch function and low-level input signal detection. The channels’ input signal level determines whether the output is active. The Diodes Inc. PI3EQX32914 has an adaptive power management feature to maximize battery life for power-sensitive consumer devices.
