The device provides programmable equalization, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference.
PI2EQX3431 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 before 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 (CE=1) and operating, that channels input signal level (on xIN+/-) 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 CE = 0, the device enters a low power standby mode.
