MN88831
PCM Audio Decoder LSI for Satellite Broadcasting Tuners
(Includes Built-In Digital Filter and D/A Converter)
Overview
The MN88831 greatly streamlines set design by incor-
porating a satellite broadcasting PCM audio decoder, a
switched capacitor D/A converter, and analog post filter
to a single chip.
Features
Built-in digital filter using 8-fold oversampling
Built-in tertiary -noise shaping D/A converter
Reduced jitter noise through use of switched
capacitor configuration
Built-in analog post filter
Built-in digital de-emphasis circuit
Choice of microcomputer interfaces with selector pin:
3-wired serial interface or I2C interface
Muting function supporting following settings
• Pay-per-view flag detection
• Error frequency detection
• Detection of control code bit-7
Built-in general-purpose microcomputer I/O port
Bit stream input pin supporting 0.4 VP-P input
Applications
Satellite broadcasting tuners (BS, CS)
