This value is only guaranteed in lab.
1). Measured in the evaluation board (see Chapter 4), worst case in band.
2). This is the level of divider interferences close to the IF frequency. For example channel S3:
fOSC = 158.15 MHz, 1/4 fOSC = 39.5375 MHz. Divider interference is measured in the evaluation
board (see Chapter 4).
3). Channel S02 beat is the interfering product of fRF, fIF and fOSC of channel S02, fbeat = 37.35 MHz.
The possible mechanisms are fOSC - 2 x fIF or 2 x fRFpix - fOSC. Measured in the evaluation board
