A product Line of Diodes Incorporated PI3EQX1004B1 2-Port USB3.1 Gen-2 10Gbps ReDriver Features Description II5 & 10Gbps serial link with linear equalizer The PI3EQX1004B1 is a low power, high performance 10.0 Gbps 2-Port USB 3.1 linear ReDriverTM designed specifically for the USB 3.1 protocol. IIUSB3.1 and USB3.0 Compatible IIFull Compliancy to USB3.1 Super Speed Standard IIFour 10Gbps differential signal pairs The device provides programmable equalization, and flat gain to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI3EQX1004B1 supports two 100 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. IIPin Adjustable Receiver Equalization IIPin Adjustable Flat Gain II100 Differential CML I/O's IIAutomatic Receiver Detect IIAuto "Slumber" mode for adaptive power management IISingle Supply Voltage: 3.3V The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver. Each channel operates fully independently. The channels' input signal level determines whether the output is active. IIPackaging: 42-pin, TQFN 3.5 x 9mm (ZH42) The PI3EQX1004B1 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.

"Low" - Channel is in power down mode. GND Supply Ground Input Connect to VDD is recommended Power Management Notebooks, netbooks, and other power sensitive consumer devices require judicious use of power in order to maximize battery life. In order to minimize the power consumption of our devices, Diodes has added an additional adaptive power management feature. When a signal detector is idle for longer than 1.3ms, the corresponding channel will move to low power mode ONLY. (It means both channels will move to low power mode individually). In the low power mode, the signal detector will still be monitoring the input channel. If a channel is in low power mode and the input signal is detected, the corresponding channel will wake-up immediately. If a channel is in low power mode and the signal detector is idle longer than 6ms, the receiver detection loop will be active again. If load is not detected, then the Channel will move to Device Unplug Mode and monitor the load continuously. If load is detected, it will return to Low Power Mode and receiver detection will be active again per 6ms.
