Differential Channel Serial Re Driver 20-Pin SSOP T/R

Pericom Semiconductor’s PI2EQX3211B is a low power, signal re-driver. The device provides programmable equalization, by using 2 select bits, EQA and EQB, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI2EQX3211B supports two 100 Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or to extend the signals across other distant data pathways on the user’s platform. The integrated equalization circuitry provides fl exibility with signal integrity of the signal before the re-driver. Whereas the integrated de-emphasis circuitry provides fl exibility with signal integrity of the signal after the re-driver.A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independantly. When the channels are enabled (EN=1) and operating, that channels input signal level (on xI+/-) determines whether the output is enabled. If the input level of the channel falls below the active threshold level (Vth-) then the outputs are driven to the common mode voltage.In addition to providing signal re-conditioning, Pericom’s PI2EQX3211B also provides power management Stand-by mode operated by the Enable pin.
