* 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.

Per Output

1. VCMR is the difference from the most positive side of the differential input signal. Normal operation is obtained when the “High” input is within

the VCMR range and the input lies within the VPP specification.

2. The MPC972/973 outputs can drive series or parallel terminated 50

Ω (or 50Ω to VCC/2)transmissionlinesontheincidentedge(seeApplications

Info section).

3. Inputs have pull–up/pull–down resistors which affect input current.

4. Special thermal handling may be required in some configurations.

5. 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.
