Notes
1. Some parameters can be decreased at V
2. This parameter is not tested during production and is only given as application information.
3. For a higher AC load a resistor application is possible.
4. Measured without input signal but AGC adjusted corresponding to following input level
5. Calculation of the PLL loop filter by using following formulae, valid under the condition for the damping factor
6. The reference input at pin S2 is able to operate as a one-pin crystal oscillator as well as an input terminal with
7. The value of C
8. The tolerance of the reference frequency determines the accuracy of the low IF. The tolerance of f
