Compact Disk Player DSP
LC78632RE
Overview
The LC78632RE is a compact disc D/A signal-processing
LSI for Video-CD players that provides a variable clock
error correction (VCEC) mode. The LC78632RE
demodulates the EFM signal from the optical pickup and
performs de-interleaving, error detection, error correction,
digital filtering, and other processing. The LC78632RE
includes an on-chip 1-bit D/A converter, and executes
commands sent from a control microprocessor.
Features
VCEC support
Built-in PLL circuit for EFM detection (supports 4
×
playback)
18KB RAM on chip
Error detection and correction (corrects two errors in C1
and four errors in C2)
Frame jitter margin: ±8 frames
Frame synchronization signal detection, protection, and
insertion
Dual interpolation adopted in the interpolation circuit.
EFM data demodulation
Subcode demodulation
Zero-cross muting adopted
Servo command interface
2fs digital filter
Digital de-emphasis
Built-in independent left- and right-channel digital
attenuators (239 attenuation steps)
Supports the bilingual function
Left/right swap function
Built-in 1-bit D/A converter (third-order
noise
shaper, PWM output)
Built-in digital output circuit
CLV servo
Arbitrary track jumping (of up to 255 tracks)
Variable sled voltage (four levels)
Six extended I/O ports and 2 extended output ports
Built-in oscillator circuit using an external 16.9344 MHz
or 33.8688 MHz (for 4
×
playback) element
Supply voltage: 4.5 to 5.5 V
