s This value is only guaranteed in lab.

1). Measured in the evaluation board. (see Chapter 4)

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. Measured in the evaluation board. (see Chapter 4)

3). Channel 6 beat is the interfering product of fRFpix + fRFsnd - fOSC of channel 6 at 42 MHz. Measured in

the evaluation board. (see Chapter 4)

4). Channel A-5 beat is the interfering product of fRFPIX + fRFSND - fOSC of channel A-5, fbeat = 45.5 MHz.

The possible mechanisms are fOSC - 2 x fIF or 2 x fRFpix - fOSC. Measured in the evaluation board.
