CMOS IC
LC896431
MD Decoder IC
Overview
The LC896431 implements playback signal processing
that conforms to the MiniDisc format standards. This
device was designed to form a chip set in conjunction with
a SANYO RF amplifier IC.
Features
• Fabricated in a CMOS process for low power
• An application system can be created easily by
combining this IC with a SANYO RF amplifier IC.
• Provides digital servo functions and a VCEC for high-
speed access.
• Allows the creation of optimal systems by integrating
8× oversampling digital filters, a 1-bit D/A converter,
and a low-pass filter on the same chip.
Functions
• Full complement of automatic adjustment functions
• Intensity, defect, and shock detection
• Both CLV and CAV control
• VCEC circuit
• Automatic adjustment functions
• High-performance ATRAC3 decoder
• EFM data demodulation
• Error detection and correction (C1: E12, C2: E24)
• Error correction RAM
• Intelligent commands
• Anti-shock control
• ADIP demodulation and decoding
• Digital servo
• EFM ACIRC decoding
• High-performance 1-bit D/A converter
• Built-in second-order low-pass filter for audio output
• Power saving function for the stopped and paused states
