PI2EQX502T supports two 100? differential cml data i/os between the protocol asic to a switch fabric, over cable, or to extend the signals across other distant data pathways on the users 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. 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 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. xi + cml cm l limiting a mp e qualizer s ignal detection p ower management - repeated 2 times - xi ? xo + x o ? eq_x tablet pc multi-function printer pericom usb3.0 redriver pericom usb3.0 redriver pericom usb3.0 redriver external storage device usb 3.0 cable usb 3.0 cable digital camera features product databrief new product brief
