A product Line of Diodes Incorporated PI3EQX1001 1-Channel USB3.1 GEN-2 ReDriver Features Description 5 & 10Gbps serial link with linear equalizer. e PTh I3EQX1001 is a low power, high performance 10.0 Gbps USB3.1 and USB3.0 Compatible 1-Channel USB 3.1 linear ReDriver designed specicfi ally for the Full Compliancy to USB3.1 Super Speed Standard USB 3.1 protocol. Single 10Gbps differential signal pairs e dTh evice provides programmable equalization, and flat gain Pin Adjustable Receiver Equalization to optimize performance over a variety of physical mediums by Pin Adjustable Flat Gain reducing Inter-Symbol Interference. PI3EQX1001 supports one 100 Differential CML I/Os 100 Differential CML data I/Os between the Protocol ASIC to Automatic Receiver Detect a switch fabric, over cable, or to extend the signals across other AutoSlumbe mode for adaptive power management distant data pathways on the users platform. Single Supply Voltage: 3.3V e iTh ntegrated equalization circuitry provides flexibility with Packaging: signal integrity of the signal before the ReDriver. The channels 18-pin, X2QFN 2x2 mm (XUA18) input signal level determines whether the output is active. e PTh I3EQX1001 also includes an automatic receiver detect function. The receiver detection loop will be active again if the corresponding channels 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.
