PI3EQX1002E/PI3EQX1004E Linear ReDrivers™

Diodes' PI3EQX1002E and PI3EQX1004E are high power, 1-port and 2-port, respectively, linear ReDrivers compliant with USB 3.1 Gen. 2, 10 Gbps and are backward compatible with USB 3.1 Gen. 1, 5 Gbps. The devices provide programmable equalization and flat gain to optimize performance over a variety of physical mediums by reducing intersymbol interference (ISI). Supporting two 100 Ω 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. Each channel operates fully independently with the channels' input signal determining whether the output is active. The ReDrivers also include an automatic receiver detect function. The receiver detection loop will be active again if the corresponding channel's signal detector is idle for longer than 7.3 mS, and the channel will then move to unplug mode if the load is not detected or it will return to low power mode (slumber mode) due to inactivity.
