Texas Instruments  SN65LVPE504RUAR

The SN65LVPE504 is a quad channel, half four lane PCIe redriver and signal conditioner supporting data rates of up to 5.0Gbps. The device complies with PCIe spec revision 2.1, supporting electrical idle and power management modes.

Programmable EQ, De-Emphasis and Amplitude Swing

The SN65LVPE504 is designed to minimize the signal degradation effects such as crosstalk and inter-symbol interference (ISI) that limits interconnect distance between two devices. The input stage of each channel offers selectable equalization settings that can be programmed to match loss in the channel. The differential outputs provide selectable de-emphasis to compensate for the anticipated distortion PCIe signal will experience. Both equalization and de-emphasis levels for all 4 channels are controlled by the setting of signal control pins EQ, DE and OS.

See Table 1 for EQ, DE and OS setting details.
