1) Values are referred to
2) The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF).
3) Local oscillator FM modulation resulting from I
4) (N+5) -1 MHz is defined as the input level of channel N+5, at frequency 1 MHz lower, causing 100 kHz FM
5) Impedance measured with differential 2-port measurement at input or output. Input and output pins directly
6) Limits are related to the tank circuit used in the application board. Frequency bands may be adjusted by the
7) The supply ripple susceptibility is a sideband measurement using a spectrum analyzer connected to the IF
8) This is the level of divider interferences close to the IF frequency. For example channel S3: f
9) Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection has
10) The reference frequency rejection is the level of reference frequency sidebands (e.g. 62.5 kHz) related to the
