LMK04828. To accomplish this, send the 10-MHz reference output from the signal generator and connect it to J6 (CLKIN) of the ADS54J20EVM. This causes LED D1 to illuminate indicating the LMK VCXO source is locked to the external reference clock. The provided LMK configuration files will work in this mode as well. -
Page 15: Analog Input Options
10-MHz signal can be brought into the CLKIN input to synchronize to external instruments. This is the board default mode of operation. Analog Input Options The ADS54J20EVM allows for a differential analog input configuration in addition to the default using the single-ended transformer-coupled input. This option is described in the following section. 5.2.1 Differential Input The analog input transformers can be bypassed in favor of a differential input source. -
