* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or
conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute-maximum-rated conditions is not
implied.

THERMAL CHARACTERISTICS
Proper thermal management is critical for reliable system operation. This is especially true for high fanout and high drive
capability products. Generic thermal information is available for the Motorola Clock Driver products. The means of calculating die
power, the corresponding die temperature and the relationship to longterm reliability is addressed in the Motorola application
note AN1545.

1. The MPC972 outputs can drive series or parallel terminated 50
(or 50
to VCC/2) transmission lines on the incident edge (see Applications
Info section).
2. Inputs have pull–up/pull–down resistors which affect input current.
3. Special thermal handling may be required in some configurations.

4. Maximum input reference frequency is limited by the VCO lock range and the feedback divider or 100MHz, minimum input reference frequency
is limited by the VCO lock range and the feedback divider.
