Figure 23. PCI Express Analog Voltage Filter Circuit

Serial to

Parallel PCI

Bridge

Additional Notes:

Place C as close as possible to package pin.

R must be placed between VCC15 and L.

Route VCCAPE and VSSAPE as differential traces.

VCCAPE and VSSAPE traces must be ground referenced (No VCC15 references).

Max total board trace length = 1.2”.

Min trace space to other nets = 30 mils.
