CD Digital Signal Processor

Sony Semiconductor 

CD Digital Signal Processor

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.
