LC78632RE
Compact Disk Player DSP
Preliminary
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
