Multistandard hybrid IF processing
[1]
At internal Nyquist processing off (W7[0] = 1) it is mandatory to set the internal video level bit VIDLEVEL to
normal (W7[4] = 0).

SIFLEVEL
SIF level reduction
1 = internal SIF level is reduced by 6 dB (only for AM sound)
0 = internal SIF level is normal
4
VIDLEVEL video level reduction
1 = internal video level is reduced by 6 dB
0 = internal video level is normal
3
OPSTATE
output state; PORT = 1
1 = output port is HIGH (external pull-up resistor needed)
0 = output port is LOW
2
PORT
port or VIF AGC monitor
1 = pin MPP1 is logic output port; level depends on OPSTATE
0 = pin MPP1 is VIF AGC monitor output; independent on OPSTATE
1
FILOUTBP external lter output signal source; see Figure 9
1 = signal for external lter is obtained behind internal BP lter
0 = signal for external lter is obtained behind SIF mixer
0
NYQOFF
internal Nyquist processing
1 = internal Nyquist processing off[1]
0 = internal Nyquist processing on
