Note 1:
Note 2:
System performance is specified for typical digital system timing specifications.
The actual minimum ‘tclpw’ is dependent on the external capacitor value, the CIS output impedance.
During ‘clamp’ operation, sufficient time needs to be allowed for the external capacitor to charge up to the
correct operating level. Refer to the description in Theory of Operation, CIS Config.
