PI2EQX5864C
5.0Gbps 4-Lane PCIe 2.0 ReDdriver
with Equalization, Emphasis and I2C Control
Output Conguration
The PI2EQX5864C 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 with good eye opening. Control of output congura-
tion is grouped for the A and B channels, so that each channel within the group has the same setting.
Output conguration can be set via I2C when the mode pin is LOW. The Output Swing Control table shows available conguration
settings for output level control, as specied by the SELx_y registers.

Emphasis settings are determined by the state of the Dx_y input pins and conguration registers, as shown below. De-Emphasis is
selected as the default power-on mode in following the PCI Express specication, but can be changed to Pre-emphasis via repro-
gramming the Loopback and Emphasis Control register using the I2C interface.
Input Level Detect
An input level detect and output squelch function is provided on each channel to eliminate re-transmission of input noise. A continu-
ous signal level below the Vth- threshold causes the output driver to go to a high-impredance state, so that both the positive and nega-
tive output signal are pulled to VDD by the internal pull-up resistors. This feature supports L0S PCI Express Electrical Idle state.
