LC78684E

MP3 Decoder for Compact Disc Players

Overview

x CD-ROM Decoding Functions

The LC78684E integrates, on a single chip, CD-ROM

signal-processing functions, MP3 signal-processing func-

tions, and CD-DA shockproof signal-processing functions.

The LC78684E achieves significant power savings by

implementing signal-processing functions using hard-

wired structures.

A CD player that supports playback of MPEG audio

(MP3) recorded on CD media as well as CD-DA

shockproof playback can be implemented by combining

this IC with a CD DSP, DRAM, and audio D/A converter,

and other circuits.

ꢀ Supports CD-ROM modes 1 and 2 (forms 1 and 2)

ꢀ Faithfully reproduces data stored on CD-ROM discs

using CD-ROM error correction functions.

ꢀ Header and sector management

ꢀ Supports playback speeds up to 4×.

ꢀ In addition to data buffering also supports C2 error

flag buffering.

ꢀ Provides external serial output of decoded CD-ROM

data.

x CD-DA Playback Functions (Shockproof support)

ꢀ Shockproof operation for about 180 seconds (com-

pressed mode) when 64M DRAM is used.

ꢀ Shockproof function supports compressed, uncom-

pressed, and data through modes.

ꢀ VCEC (variable speed) supports up to 4×-speed play-

back.

x Audio Signal Processing

ꢀ Serial audio signal output using LRCK, BCK, and

DATA signals.

(I²S format, either 16-bit or 20-bit precision PCM

output, data-slot supports 16-bit, 24-bit, and 32-bit

modes)

ꢀ Digital bass boost function (4 modes), attenuator

function, and muting (ꢀf, ꢀ12 dB)

ꢀ Provides a base clock (384 fs) output pin for use with

external digital filters and D/A converters.

x DRAM Interface

Features

x MP3 Decoding Functions (MPEG audio standard

[ISO/IEC 11172-3] layer 3)

ꢀ Decodes to a digital audio signal MP3 data decoded

by the CD-ROM decoder and outputs that audio

signal.

ꢀ Supports all bit rates, including variable bit rate

operation.

ꢀ Supports the following sampling rates.

MPEG1 (Fs = 32 K, 44.1 K, 48 K)

MPEG2 (Fs = 16 K, 22.05 K, 24 K)

MPEG2.5 (Fs = 8 K, 11.025 K, 12 K)

ꢀ Can read out the MPEG header and ancillary data.

ꢀ Automatically mutes the signal on CRC errors using

an MP3 CRC check function.

ꢀ External MPEG serial data input function supports

memory card playback.

ꢀ Supports the use of from 1M to 64M of external

DRAM (EDO, 2CAS, 16-bit data bus memory)

ꢀ Supports allocation of a user area in DRAM during

CD-ROM (MP3) playback.
