Notes:

2* It’s assumed that phase noise test is performed under static conditions (no vibration), in still air, and care is taken for minimizing EMI. Cross correlation

method is recommended with equipment having adequate performance

3* Longer storage time, especially at low temperatures, may affect both retrace and setability parameters. It may require few days on power for re-stabilization

4) All parameters, unless otherwise specified, are at nominal conditions, i.e.: T=25°C, Nominal Vcc & Nominal Load.

5) Additional retrace from OSC DIS to OSC EN is within normal aging and temperature stability range of frequency deviation. Cannot be specified separately.

6* E grade phase noise test is performed with internal bias to Vc = 2.5 V, provided by resistive divider from Vref. Resistors are low noise metal film. After the

test the bias is removed.
