TDA8204B Datasheet, PDF (9/12 Pages) STMicroelectronics – NICAM DECODER

TDA8204B
IBG : Standard I (don’t care)
FSn : Set to Auto NICAM (if NICAM fails, FM
mono is selected)
FN2 : Not used
SYN : Synthesizer selected
2 - Hardware Configurable Pins
2.1 - TDA8204B - PIN 6 - (RSW)
- as an output :
status of the RSW switch
- 0 = FM mono
- 1 = NICAM
- as an input :
- 0 = FM mono (forced)
2.2 - TDA8204B - PINS 34/35 - (SEL0/SEL1)
(see Figure 7)
- to select the language in case of bilingual opera-
tion
- selected value is related to LA0 and LA1
Figure 7
LA0 LA1
As the I²C bus is not used LA0 and LA1 = 0
(power-ON condition) / SEL0 = Q0, SEL1 = Q1
The 4 choices are summarized in the table below.

VII - 2.3. TDA8204B - PIN 25 - (MUTE)
- as an output :
status of the DAC
- 0 = unmuted
- 1 = muted
- as an input :
- 0 = unmute DAC (forced)
