1) Values are referred to the application given in Figure 9 and f
IF = 36 MHz, unless stated otherwise.
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
2C communication is measured at the IF output using a
modulation analyzer with a peak to peak detector ((P
+ + P-) / 2) and a post detection filter 20 Hz - 100 kHz. The
I
2C messages are sent to the tuner in such a way that the tuner is addressed but the content of the PLL registers
are not altered. The refresh interval between each data set shall be 20 ms to 1 s.
4) (N+5) -1 MHz is defined as the input level of channel N+5, at frequency 1 MHz lower, causing 100 kHz FM
sidebands 30 dB below the wanted carrier.
5) Impedance measured with differential 2-port measurement at input or output. Input and output pins directly
connected to measurement equipment with 50
strip lines.
6) Limits are related to the tank circuit used in the application board (see Figure 9). Frequency bands may be
adjusted by the choice of external components.
7) For wide loop filter application (see Figure 11).
8) For narrow loop filter application (see Figure 10).
