CMOS IC
LC78628E
Compact Disc Player DSP with Built-in HDCD Decoder
®
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.
Functions
• Full decoding and playback for discs encoded with the
HDCD technique developed by Pacific Microsonics,
Inc.
• 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.
• Controls the disc motor speed using a frame phase
difference signal created based on the reproduced clock
signal and the reference clock.
• 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.
