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.
