PI2EQX5804C
5.0Gbps 4-Lane PCIe 2.0 ReDriver with
Equalization & Emphasis
Equalizer Conguration
The PI2EQX5804C input equalizer compensates for signal attenuation and Inter-Symbol Interference (ISI) re-
sulting 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.
Equalizer conguration is performed in two ways determined by the state of the MODE pin. When the device
rst powers up, the SELx_[A:B] input pins are read into the appropriate control registers to set the equalization
characteristic. If the MODE pin is low, reprogramming of these control registers via I2C is allowed.
Each group of four channels, A and B, has separate equalization control, and all four channels within the group
are assigned the same conguration state. The Equalizer Selection table below describes pin strapping options
and associated operation of the equalizer. Refer to the section on I2C programming for information on soft-
ware conguration of the equalizer.

Output Conguration
The PI2EQX5804C provides exible 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 open-
ing. Control of output conguration is grouped for the A and B channels, so that each channel within the
group has the same setting.
Output conguration is performed in two ways depending on the state of the MODE pin. When the device
rst powers up, the Sx_[A:B], and Dx_[A:B] input pins are read into the appropriate control registers to set the
power-on state. If the MODE pin is low, reprogramming of these control registers via I2C is allowed.
The Output Swing Control table shows available conguration settings for output level control, as specied
using the Sx_y pins and registers.
