10) Limits are related to the tank circuit used in the application board (see Chapter 3 on page 27). Frequency bands
11) The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
12) The frequency drift is defined as a change in oscillator frequency if the ambient temperature varies from T
13) The switch-on drift is defined as a change in oscillator frequency between 5 s and 15 min after switch-on. The

A sinewave signal with a frequency of 500 kHz is superposed onto the supply voltage (see 4.5.8 on page 58).
The amplitude of this ripple is adjusted to bring the 500 kHz sidebands around the IF carrier to a level of 53.5
