TDA8296

Digital global standard low IF demodulator for analog TV and FM radio

[1]

Before activating mono sound, the TV standard needs to be set via easy programming

AUTO_MUTE

R/W

When active, the mono sound signal is muted if the horizontal lock flag

(N_H_LOCK) disappears. This setting only makes sense in case the sound

DAC output is also set to mono sound (SSIF_SND[1:0] = 01). FOR_MUTE

has no function if SSIF_SND[1:0] =10.

off

don’t care if SSIF output is chosen (SSIF_SND[1:0] = 10)

1 and 0 SSIF_SND[1:0]

R/W

either mono sound or SSIF can be chosen for the sound DAC output

mono sound output level

0 0001

−12 dB nominal; implemented for flexibility reasons. With this setting, the

adaptation to different standard requirements can be done.

0 0010

−6 dB nominal; implemented for flexibility reasons. With this setting, the

adaptation to different standard requirements can be done. It is chosen for FM

radio because of the large FM deviation involved.

0 0100

Nominal setting; FM deviations up to 100 kHz can be processed without sound

DAC clipping. The clipping level is 535 mV (RMS) typically.

0 1000*

+6 dB nominal; chosen for M/N standard due to less nominal frequency

deviation

1 0000

+12 dB nominal; implemented for flexibility reasons. With this setting, the

adaptation to different standard requirements can be done.
