CMOS IC

LC78602NE

Compact Disc Player DSP with

Built-in Microcontroller

symbol data.

Overview

• Separates the subcode data from the EFM signal and

outputs that data to the internal control processing block.

• After applying a CRC check to the subcode Q signal,

outputs that signal to the internal control processing

block.

• Buffers the demodulated EFM signal data in internal

RAM and compensates for ±4 frames of jitter due to

disc speed fluctuations.

• Performs unscrambling and deinterleaving by reordering

the demodulated EFM signal data to the stipulated order.

• Performs error detection and correction and flag

processing (C1: dual errors, C2: dual errors)

• The C2 flags are set based on the C1 flags and the result

of the C2 processing, and the signal is interpolated or

previous value hold is applied based on the C2 flags.

Dual interpolation is adopted in the interpolation circuit.

Previous value hold is applied if two or more

consecutive errors are indicated by the C2 flags.

• Performs track jump, focus start, disc motor start/stop,

muting on/off, track count, and other operations under

control of the internal control processing block.

• Provides digital outputs.

The LC78602NE CMOS IC implements compact disc

player signal processing, servo control, LED display, key

input acquisition, and remote controller processing

without requiring control by a separate microcontroller.

The basic functions provided include demodulation of the

EFM signal from the optical pickup, deinterleaving, error

detection and correction, 8× oversampling digital filters,

D/A converter (with built-in analog low-pass filter), LED

driver, remote controller processing, key acquisition, and

control processing. Thus this IC can provide excellent

cost/performance characteristics when implementing a

low-end CD player.

Functions

• Implements CD play/pause, disc stop, track selection,

fast forward, reverse, repeat mode playback of 1 track or

the whole disc, programmed play (setup, play, and clear)

of up to 16 tracks, and random repeat play under the

control of key input or remote controller input.

<Signal-Processing Block>

• Slices an input high-frequency signal at an accurate

level, converts the EFM signal, and generates a clock

with an average frequency of 4.3218 MHz using a PLL

circuit that performs a phase comparison with an

internal VCO.

• Accurately generates not only the reference clock but

also all necessary internal timings using an external

16.9344MHz crystal.

• Controls the disc motor speed using a frame difference

signal created based on the reproduced clock signal and

a reference clock.

• Generates D/A converter input signals with continuity

improved by 8× oversampling digital filters.

• Includes on-chip third-order noise shaper delta-sigma

D/A converters with built-in analog low-pass filter.

• Digital deemphasis circuit

• Adopts zero-cross muting.

• On-chip LED drivers for 7 segment 2-digit display plus

play, program, repeat, and random indicators

• Key matrix circuit with 1 input and 8 outputs for an

8-key matrix

• Performs detection, protection, and interpolation for the

frame synchronizing signal to assure stable data readout.

• Demodulates the EFM signal, converting it to 8-bit

• Supports remote controller input.
