Notes:

1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions

is not guaranteed.

2. This voltage is the input to the filter discussed in Section 9.2, “PLL Power Supply Filtering,” and not necessarily the

voltage at the AVDD pin which may be reduced from VDD by the filter.
