Sanyo LC896431 Specifications

Ordering number : ENN 6891

11901RM (OT) No.6891-1/6

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

Notes: 1. Supply all power supplies at less than the maximum gradient of 0.4 V/ms, and implement a delay of 10 ms or longer for current to go from 0 V to

2.4 V.

2. Supply all power supplies simultaneously so that there are no delay differences among them.

3. Supply 0 to the RESETB pin only upon power application, and following power application, supply 1 and use with this value.
