Bit Allocation Read/Write
9) The supply ripple susceptibility is a sideband measurement using a spectrum analyzer connected to the IF
output. An unmodulated RF signal with a level of 80 dBV is applied to the test board RF input. A sinewave
signal with a defined frequency is superposed onto the supply voltage (see Figure 21). The specified value is
the worst case in the frequency range.
10) This is the level of divider interferences close to the IF frequency. For example channel S3: f
OSC = 158.15 MHz,
1/4 f
OSC = 39.5375 MHz. The rejection has to be greater than 60 dB for an SAW driver output of 100 dBV.
11) Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection has
to be greater than 60 dB for an SAW driver output of 100 dBV.
12) The reference frequency rejection is the level of reference frequency sidebands according to the application
circuit (166.67 kHz for DVB-T standard, 142.86 kHz for ISDB-T standard or 62.5 kHz for ATSC standard)
related to the carrier. The rejection has to be better than 60 dB for a SAW driver output level of 100 dBV. In
hybrid application the rejection is valid for the digital reference frequency (166.67 kHz for DVB-T/PAL standard,
or 142.86 kHz for ISDB-T/NTSC standard), but any lower analog reference frequency may reduce this
rejection.
13) Channel S02 beat is the interfering product of f
RFpix, fIF and fOSC of channel S02, fBEAT = 37.35 MHz. The possible
mechanisms are f
OSC - 2 x fIF or 2 x fRFpix - fOSC.
