External clock source characteristics

High-speed external user clock generated from an external source

Data based on a differential IDD measurement between DAC in reset configuration and continuous DAC

conversion of VDD/2. DAC is in buffered mode, output is left floating.

Including supply current of internal reference voltage.

Table 26.
