Zarlink Semiconductor Inc.

Note 1:

for an input signal frequency of less than 2GHz, the slew rate of the sinewave signal becomes progressively too slow for the

divider.

† Input sensitivity and output power values assume 50 Ohm source and load impedances

For details of the test set-up, refer to the Application Note for RF Prescalers.

The following graph summarizes the Input and Output Characteristics table:
