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.
