The first step to confirm that the device is still functional is to power up the device as specified in the datasheet. Probe the power supplies to confirm that power is reaching the part as intended. Secondly, probe the VCAP1-3 pins to verify that the device is powering up internally. Compare these voltages to the list below: VCAP1: AVSS + 1.2V VCAP2: (AVDD+AVSS)/2 VCAP3: AVDD + 1.9V Third, probe the reference voltage to confirm that it has powered up correctly. Lastly, either configure or enable your clock source and probe the /DRDY pin to verify that it is pulsing at the default output datarate. Link to BIOFAQ homepage here .
