TDA9850中文资料I2C-bus controlled BTSC stereo/SAP decoder数据手册恩XP规格书

描述 Description

GENERAL DESCRIPTION
The TDA9850 is a bipolar-integrated BTSC stereo/SAP decoder (I2C-bus controlled) for application in TV sets, VCRs and multimedia.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.
