Footnotes:

1) Standard frequency stability (±20,±25,±50ppm & others available)

2) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.

3) Internal high frequency power source decoupling.

4)

If phase noise data at a particular frequency is needed, contact factory.

5) All parameters, unless otherwise specified, are at

nominal conditions, ie: T=25°C, Nominal Vcc &

Nominal load.
