Notes:

*. For highest operating temperature higher than 70°C the power consumption will be higher (about 20% for 85°C).

Values listed are for test in still air environment, the values will go up while testing in the temperature chamber.

2*. It is recommended to specify Slope option "N" for Ultimate Phase noise performance. For recommended phase

noise test, contact factory. It's assumed that phase noise test is performed under static conditions (no vibration),

in still air, and care is taken for minimizing EMI.

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, ie: T=25°C, Nominal Vcc & Nominal Load.
