Preliminary speciﬁcation

I2C-bus controlled BTSC stereo/SAP

decoder and audio processor

TDA9852

FEATURES

• Quasi alignment-free application due to automatic

adjustment of channel separation via I2C-bus

• High integration level with automatically tuned

integrated filters

• Input level adjustment I2C-bus controlled

• Alignment-free SAP processing

• dbx noise reduction circuit

• Power supply

• I2C-bus transceiver.

Stereo decoder

• Stereo pilot PLL circuit with ceramic resonator,

automatic adjustment procedure for stereo channel

separation, two pilot thresholds selectable via I2C-bus.

Audio processor

• Selector for internal and external signals (line in)

• Automatic volume level control

(control range +6 to

−15 dB)

• Interface for external noise reduction circuits

• Volume control (control range +16 to −71 dB)

• Special loudness characteristic automatically controlled

in combination with volume setting (control range 28 dB)

• Audio signal zero crossing detection between any

volume step switching

• Mute control at audio signal zero crossing

• Mute control via I2C-bus.

GENERAL DESCRIPTION

The TDA9852 is a bipolar-integrated BTSC stereo

decoder with hi-fi audio processor (I2C-bus controlled) for

application in TV sets, VCRs and multimedia.
