PI3EQX7742ST 5.0 Gbps, 2-port, USB 3.0 ReDriver™ with Digital Confguration Features Description ÎÎUSB 3.0 compatible Pericom Semiconductor’s PI3EQX7742ST is a low power, high performance 5.0 Gbps signal ReDriver™ designed specifically for the USB 3.0 protocol. The device provides programmable equalization, De-Emphasis, and input threshold controls to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI3EQX7742ST supports four 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 low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. When the channels are enabled EN_x# = 0 and operating, that 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. In addition to signal conditioning, when EN_x# =1, the device enters a low power standby mode. The PI3EQX7742ST also includes a fully programmable receiver detect function. When the RxDet pin is pulled high, automatic receiver detection will be active. The device will then move to power down due to inactivity.

With internal 200kΩ pull-up resistor. Center Pad GND GND Supply Ground. Adaptive Auto Power Down or "Slumber" Mode 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, Pericom has added an additional adaptive auto power down feature. When a signal detector is idle for longer than 5ms, 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 the channel is in low power mode and the input signal is detected, the corresponding channel will wake up . The device can also be forced into power down mode through the use of the EN_x# pins however this would require the use of GPIO pins to control. 12-0156 2 www.pericom.com PS-0.2 07/03/12 PI3EQX7742ST 5.0 Gbps, 2-port USB 3.0 ReDriver™ with Digital Configuration Configuration Table EN_x# R X Det_xx Function Input R Output R 1 X Channel disable if EN_A#, EN_B#, EN_C#, and EN_D# are high, Chip Power Down Hi-Z Hi-Z 0 1 Chip and channel enabled, receiver detect is active 50Ω / Hi-Z* 50Ω / Hi-Z* 0 0 Chip and channel enabled, receiver detect is not active 50Ω 50Ω * Refer to pin 20 & 41 description Mode Adjustment Equalization Setting: EQ_A/B/C/D are the selection pins for the equalization selection for each direction.
