ADS127L21EVM-PDK: How to sync-up the EVM clock with external clock?

Hello Chen,

There is no clock synchronization function, but you can provide an external clock instead of using the onboard oscillator.

You can move jumper JP6 to the 'Ext Clk' position, and then connect an external clock source (CMOS, 2.5V, square-wave) to SMA connector J14.
