PCI Express Analog Voltage Filter Circuit

Note: .
•
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.
