Product Description

The PI3EQX7742 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, De-Emphasis, and input threshold controls to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. The PI3EQX7742 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, whenEN_x#=1, the device enters a low power standby mode. The PI3EQX7742 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.
