I2C-bus controlled BTSC stereo/SAP decoder
Preliminary specification
TDA9850
FEATURES
Quasi alignment-free application due to automatic
adjustment of channel separation via I2C-bus
Dbx noise reduction circuit
Dbx decoded stereo, Second Audio Program (SAP) or
mono selectable at the AF outputs
Additional SAP output without dbx, including
de-emphasis
High integration level with automatically tuned
integrated filters
Input level adjustment I2C-bus controlled
Alignment-free SAP processing
Stereo pilot PLL circuit with ceramic resonator,
automatic adjustment procedure for stereo channel
separation, two pilot thresholds selectable via I2C-bus
Automatic pilot cancellation
Composite input noise detector with I2C-bus selectable
thresholds for stereo and SAP off
I2C-bus transceiver.
GENERAL DESCRIPTION
The TDA9850 is a bipolar-integrated BTSC stereo/SAP
decoder (I2C-bus controlled) for application in TV sets,
VCRs and multimedia.
