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; Vwanted = 100 dBV; funwanted = fwanted +
5.5 MHz.
3). Local oscillator FM modulation resulting from I2C communication is measured at the IF output using a mod-
ulation analyser with a peak to peak detector ((P+ +P-)/2) and a post detection filter 30 Hz - 200 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 1s.
4). This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz fre-
quency 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 fRFpix, fIF and fOSC of channel S02, fBEAT = 37.35 MHz. The
possible mechanisms are fOSC - 2 x fIF or 2 x fRFpix - fOSC.
6). Channel A-5 beat is the interfering product of fRFpix, fIF and fOSC of channel A-5; fBEAT= 45.5 MHz. The pos-
sible mechanisms are: fOSC - 2 x fIF or 2 x fRFpix - fOSC.
7). Channel 6 beat is the interfering product of fRFpix + fRFsnd - fOSC of channel 6 at 42 MHz.
8). The IF output signal stays stable within the range of the fref step for a low level RF input up to 120 dBV.
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.
10). Limits are related to the tank circuit used in the application board (Chapter 4). Frequency bands may be
adjusted by the choice of external components.
11). The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
VCC = 5 to 4.75 V (4.5 V) or from VCC = 5 to 5.25 V (5.5 V). The oscillator is free running during this measure-
ment.
12). The frequency drift is defined as a change in oscillator frequency if the ambient temperature varies from
Tamb = 25 to 50 °C or from Tamb = 25 to 0 °C. The oscillator is free running during this measurement.
