This value is only guaranteed in lab.
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 unwanted signal (50% amplitude modulated with 1kHz) that causes a 1.1 kHz FM
modulation of the local oscillator and thus of the wanted signal; V
wanted
= 100 dBμV; f
unwanted
=
fwanted
+ 5.5 MHz.
3) Local oscillator FM modulation resulting from I
2
C communication is measured at the IF output using a
modulation analyser with a peak to peak detector ((P
+
+P
-
)/2) and a post detection filter 30 Hz - 200 kHz. The
I
2
C 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 1s.
4) 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 producing sidebands 30 dB below the level of the oscillator signal.
5) Channel S02 beat is the interfering product of f

, f
IF
and f
OSC
of channel S02, f
BEAT
= 37.35 MHz. The possible
mechanisms are f

6) Channel A-5 beat is the interfering product of f
RFpix,
f
IF
and f
OSC
of channel A-5; f
BEAT
= 45.5 MHz. The possible
mechanisms are: f
OSC
- 2 x f

or 2 x f
RFpix
- f
OSC
7) Channel 6 beat is the interfering product of f
RFpix
+ f
RFsnd
- f
OSC
of channel 6 at 42 MHz.
8) The IF output signal stays stable within the range of the f
ref
step for a low level RF input up to 120 dBμV.
9) N+5 -1 MHz is defined as the input level of channel N+5, at frequency 1 MHz lower, causing FM sidebands
30 dB below the wanted carrier.
