Description

The CXD3005R is a digital signal processor LSI for CD players. This LSI incorporates a digital servo, digital filter and 1-bit DAC.

Features

? All digital signal processing during playback is performed with a single chip

? Highly integrated mounting possible due to a builtin RAM

Digital Signal Processor (DSP) Block

? Playback mode supporting CAV (Constant Angular Velocity)

? Frame jitter free

? 0.5× to 20× continuous playback possible with a low external clock

? Allows relative rotational velocity readout

? Wide capture range playback mode

? Spindle rotational velocity following method

? Supports 1× to 20× playback by switching the builtin VCO

? The 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 Supported during 20× playback

? Noise reduction during track jumps

? Auto zero-cross mute

? Subcode demodulation and Sub Q data error detection

? Digital spindle servo (built-in oversampling filter)

? 16-bit traverse counter

? Asymmetry compensation circuit

? CPU interface on serial bus

? Error correction monitor signal, etc. output from a new CPU interface

? Servo auto sequencer

? Fine search performs track jumps with high accuracy

? Digital audio interface outputs

? Digital level meter, peak meter

? Bilingual compatible
