Description
Pericom Semiconductor’s PI2EQX5804D is a low power, PCIe®
compliant signal ReDriver™. The device provides programmable
equalization, amplification, and de-emphasis by using 8 select
bits, to optimize performance over a variety of physical mediums
by reducing Inter-symbol interference.
PI2EQX5804D supports eight 100-Ohm Differential CML
data I/O’s between the Protocol ASIC to a switch fabric, across
a backplane, or extends the signals across other distant data
pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with
signal integrity of the PCIe signal before the ReDriver, whereas
the integrated de-emphasis circuitry provides flexibility with
signal integrity of the signal after the ReDriver.
In addition to providing signal re-conditioning, Pericom’s
PI2EQX5804D also provides power management Stand-by mode
operated by a Power Down pin.

... Equalizer Configuration The PI2EQX5804D input equalizer compensates for signal attenuation and Inter-Symbol Interference (ISI) resulting from long signal traces or cables, vias, signal crosstalk and other factors, by boosting the gain of high-frequency signal components. Because either too little, or too much, signal compensation may be non-optimal eight levels are provided to adjust for any application. ...

Page 6

... Output Configuration The PI2EQX5804D provides flexible output strength and emphasis controls to provide the optimum signal to pre-compensate for losses across long trace or noisy environments so that the receiver gets a clean eye opening. Control of output configuration is grouped for the A and B channels, so that each channel within the group has the same setting. ...

... Automatic Receiver Detection is a feature that can set the number of active channels. By sensing the presence of a load device on the output, the channel can be automatically enabled for operation. This allows the PI2EQX5804D to configure itself properly de- pending on the devices it is communicating with, whether 4-lane, 3-lane, 2-lane or just 1-lane device or adapter card. ...
