CMOS IC

LC78628E

Compact Disc Player DSP with Built-in HDCD Decoder

• Performs detection, protection, and interpolation for the

frame synchronizing signal to assure stable data readout.

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

symbol data.

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

outputs that data to the control microprocessor using

serial data transfer.

Overview

The LC78628E CMOS IC implements signal processing

and servo control for compact disc players, laser disc

players, CD-V, CD-I, and similar products. It provides

functions for demodulation of the EFM signal from the

optical pickup, deinterleaving, error detection and

correction, and processing servo system commands issued

by the system microprocessor. In addition to this basic CD

functionality, it also provides HDCD (High Definition

Compatible Digital) decoding functions and CD text

functions. It also includes a built-in EFM PLL circuit.

• Slices the high-frequency input signal at an accurate

level, converts it into the EFM signal, and generates a

PLL clock with an average frequency of 4.3218 MHz

performing a phase comparison with an internal VCO.

• Accurately generates a reference clock signal and all

necessary internal timings using an external 16.9344-

MHz crystal.

2.7

• Controls the disc motor speed using a frame phase

difference signal created based on the reproduced clock

signal and the reference clock.
