external clock

Can I input an external hi precision clock to the beagle board. I need an app that need a high precision
clock from an OCXO and was wondering if one could be attached to the beagle board



There is an external clock input on the -xM version. I suggest you read the System Reference Manual for more information. I suggest you also read the TRM for the processor which uses PLL in the design. The fastest this clock can be is 54MHZ.

There is not one on the C4 version.
