TDA9897; TDA9898
Multistandard hybrid IF processing
[1]
Not recommended in combination with internal IF level set to reduced (W4[7] = 1).
[2]
At internal Nyquist processing off (W7[0] = 1) it is mandatory to set the internal video level to normal
(W7[4] = 0).

Description
7
EXTFILO
mute of output buffer of pin EXTFILO
1 = mute
0 = normal
6
VAGC
gain control voltage of VIF amplier at pin MPP; see Table 31
5
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[1]
0 = internal video level is normal
3
PORT1
output state; port 1 mode selection set to logic output port (W7[2] = 1)
1 = output port is HIGH (external pull-up resistor needed)
0 = output port is LOW
2
MODEP1
port 1 mode selection; pin PORT1
1 = logic output port; level controlled by bit PORT1 (W7[3])
0 = monitor output of VIF AGC voltage
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; see Table 24
1 = internal Nyquist processing off[2]
0 = internal Nyquist processing on
