FEATURES
DESCRIPTION
• 4 Identical Channel PCIe Equalizer/Redriver
• Support for Both PCIe Gen I (2.5Gbps) and
The SN65LVPE504 is a quad channel, half four lane
PCIe redriver and signal conditioner supporting data
Gen II (5.0 Gbps) Speed
rates of up to 5.0Gbps. The device complies with
• Selectable Equalization, De-emphasis, and
PCIe spec revision 2.1, supporting electrical idle and
