(stepsize = 1dB,range =
±
12dB in 2’s complement)
Sets the reference level for an FM signal. Note, this is also dependant on the PLL programming. For
example,with defaultsettings for the PLL, an FM deviationof 27kHzwill resultin a signal17dBbelow full
scalebeforede-emphasis.At1kHz,the internalde-emphasisgain is14dBgivinga levelof -3dB.Fullscale
outputfrom the DAC is 2V
RMS
correspondingto 0dB.and so for 1V
RMS
, PRE-FMshould be setto -3dB.

(step size = 1dB, range=
±
12dB in 2’scomplement)
Sets the reference level for a NICAM signal. For example, a full scale NICAM signal at 1kHz would be
received at -12dB before de-emphasis.Internal de-emphasis gain at this frequencyis 9dB so for 1V
RMS
,
pre-nicam shouldbe set to -3dB.
