Diodes Incorporated — Analog and discrete power solutions

The PI2EQX502T is a low power, high performance 5.0 Gbps signal ReDriver designed specifically for the USB 3.2 Gen 1 protocol. The device provides programmable equalization and De-Emphasis to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI2EQX502T supports two 100Ω Differential CML data I/O’s 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 lowlevel input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. The channels’ input signal level (on xI+/-) determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth-) then the outputs are driven to the common mode voltage.

The PI2EQX502T also includes 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 7.3mS. The channel will then move to Unplug Mode if load not detected, or it will return to Low Power Mode (Slumber Mode) due to inactivity.
