CD Digital Signal Processor

Description

80 pin QFP (Plastic)

The CXD2510Q is a digital signal processor LSI for

CD players and is equipped with the following functions.

• Wide frame jitter margin (±28 frames) due to a built-

in 32K RAM

-L051

-L01

• Bit clock, which strobes the EFM signal, is

generated by the digital PLL

• EFM data demodulation

• Enhanced EFM frame sync signal protection

• Refined super strategy-based powerful error correction

C1: double correction, C2: quadruple correction

• Quadruple-speed, double-speed and variable pitch

playback

• Noise reduction during track jumps

• Auto zero-cross mute

• Subcode demodulation and Sub Q data error

correction

• Digital spindle servo (built-in oversampling filter)

• 16-bit traverse counter

• Asymmetry compensation circuit

• Serial bus-based CPU interface

• Error correction monitor signals are output from a

new CPU interface.

Recommended Operating Conditions

°C

The VDD (min.) for the CXD2510Q varies according

to the playback speed and built-in VCO selection.

The V^DD(min.) is 4.50 V when high speed VCO

and quadruple-speed playback are selected

(variable pitch off). The V^DD(min.) for the

CXD2510Q under various conditions are as shown

in the following table.

Features

• All digital signals processed with a single chip

Dashes indicate that there is no assurance of the

processor operating. All values are for variable pitch off.

during playback

• High-integrated mounting possible due to a built-in

RAM

When the internal operation of the LSI is set to

normal-speed playback and the operating clock

of the signal processor is doubled, double-speed

playback results.

Structure

Silicon gate CMOS IC

When the internal operation of the LSI is set to

double-speed mode and the crystal oscillating

frequency is halved in low power consumption

mode, normal-speed playback results.
