9) The supply ripple susceptibility is a sideband measurement using a spectrum analyzer connected to the IF
10) This is the level of divider interferences close to the IF frequency. For example channel S3: f
11) Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection has
12) The reference frequency rejection is the level of reference frequency sidebands according to the application

related to the carrier. The rejection has to be better than 60 dB for a SAW driver output level of 100 dBµV. 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.
