NOTES:
1. These power consumption characteristics are for all the valid input interfaces and cover the worst case input and output interface combinations.
2. As a general requirement, these parts must be capable of operating at the maximum frequency under a nominal load at a reasonable operating temperature. That means that
these parts must not burn up under extended use in a typical application.
NOTE:
1. These inputs are normally wired to VDD or GND. If these inputs are switched dynamically after powerup, the function and timing of the outputs may be glitched, and the PLL may
require additional tAQ time before all datasheet limits are achieved.
