Description
Peri Semiconductor’s PI3EQX3811C Re Driver is a lowpower signal conditioner. The device provides programmable output emphasis by using 2 select bits, EMA and EMB, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI3EQX3811C 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. Whereas the integrated de-emphasis circuitry provides flexibility 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 independently. When the channels are enabled (EN=1) and operating, a channel’s input signal level (on x I+/-) 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 mon mode voltage. In addition to providing signal re-conditioning, Peri’s PI3EQX3811C also provides power management Stand-by mode operated by the Enable pin.
