1) Values are referred to the application given in
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 (see
7) For wide loop filter application (see
8) For narrow loop filter application (see
