PI2EQX3421ZHEX

The PI2EQX3421 is a low power, signal ReDriver. The device provides programmable equalization, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI2EQX3421 supports two 100-Ohm 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 flexibility with signal integrity of the signal input to 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 (CE=1) and operating, that channels input signal level (on XIN+/-) determines whether the output is enabled. 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, Pericom’s PI2EQX3421 also provides power management Stand-by mode operated by the Chip Enable (CE) pin.
