Description

The CXD2500BQ is a digital signal processing LSI designed for use in compact disc players. It has the following functions:

? Wide-frame jitter margin (±28 frames) realized by a built-in 32K RAM.

? Bit clock generated by digital PLL for strobing EFM signals. Capture range of ±150 kHz and over.

? EFM data demodulation

? Enhanced protection of EFM Frame Sync signals

? Powerful error correction based on Refined Super Strategy Error correction C1: Double correction

C2: Quadruple correction

? Double-speed playback and vari-pitch playback

? Reduced noise generation at track jump

? Auto zero-cross muting

? Subcode demodulation and subcode Q data error detection

? Digital spindle servo system (incorporating an oversampling filter)

? 16-bit traverse counter

? Built-in asymmetry correction circuit

? CPU interface using a serial bus

? Servo auto sequencer

? Output for digital audio interface

? Built-in digital level meter and peak meter

? Bilingual

Features

? All digital signals for regeneration are processed using one chip.

? The built-in RAM enables high-integration mounting.
