The AM273x SoC can operate with external clock source provided from J13 connector or clock provided from Radar FE via OSCK_FE1 on connector J1 (the HD Front End Connector).
The AM273x SoC supports externally driven clock (Square/Sine) at 40/50 MHz.
To enable an external clock source from the J13 connector, the R269 resistor must be populated on board.
To enable an external clock from the J1 connector, the R281 resistor must be populated on board.
Refer to the AM273x data sheet for external clock specifications.
