Hi, I would like to use an external reference 10 MHz TTL instead of the onboard reference clock for the LMK04828 on the ADS42JB69EVM. I will connect to J14 (REF OSC_IN). Do I need to change jumper settings? There are 3 pins with labels but not sure which one it belongs to: JP2 (CDC_CLK) or SJP3 (REF_SEL). The jumper is currently on pins 2 & 3 (default from TI).
