Board Trace:	Breakout Trace:
Trace Width > 25 mils	Trace Width > 6 mils
Trace Spacing < 10 mils	Trace Spacing < 6 mils
Trace Length < 600 mils	Trace Length < 600 mils

B2725 -01

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.
