Table 11: DC – Characteristics (under recommended operating conditions)

Note : A floating CMOS input can result in heavy internal current draws. To achieve best

performance for unused inputs an external pull-up should be added.

4.3.4

External Loop Filter Specification (Ta = -40 to 85° C)

The internal PLLs of the INGT165B and the INGR165B devices require an external RC loop filter.

It is not required to use dedicated RF R- and C-components, std components will perform correctly.
