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 Package Dimensions unit: mm 3174-QFP80E [LC78632RE] SANYO: QFP80E SANYO Electric Co.,Ltd.
