Notes

1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF).

2. This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz frequency

deviation on the oscillator signal; it produces sidebands 30 dB below the level of the oscillator signal.

3. Limits are related to the tank circuits used in Fig.19; frequency bands may be adjusted by the choice of external

components.

4. The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from

VCC = 5 to 4.75 V (4.5 V) or from VCC = 5 to 5.25 V (5.5 V). The oscillator is free running during this measurement.
