1
The reference clock input is configured to accept a differential or single-ended sine wave input or a 3 V CMOS-level pulse input.
2
REFCLK input is internally dc biased. AC coupling should be used.
3
Reference clock frequency is selected to ensure second harmonic is out of the bandwidth of interest.
4
PD inputs sent @ 400 MHz, with divide-by-4 enabled.
5
The charge pump current is programmable in eight discrete steps, minimum value assumes current sharing.
6
For 0.75 V < V
CP
< CPV
DD
– 0.75 V.
7
These differential inputs are internally dc biased. AC coupling should be used.
8
The charge pump supply voltage can range from 4.75 V to 5.25 V.
9
Output interface is differential open collector.
10
For 1 dB output compression; input power measured at 50 .
