Notes:

1. Aging rates are proportional to the operating frequency. Pull range will be adjusted accordingly to provide for

lifetime possibility to set on frequency

2. Close to the carrier phase noise deteriorates with increase in frequency.

3. All parameters, unless otherwise specified, are at nominal conditions, ie: T=25°C, Nominal Vcc & Nominal Load.
