Description

The CXD3021R 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 32× 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 32× playback by switching the built-in VCO

? The bit clock, which strobes the EFM signal, is generated by the digital PLL.

? Digital PLL master clock can be set to 2/3 the conventional one.

? EFM data demodulation

? Enhanced EFM frame sync signal protection

? Refined super strategy-based powerful error correction C1: double correction, C2: quadruple correction Supported during 32× playback

? Noise reduction during track jumps

? Auto zero-cross mute

? Subcode demodulation and Sub-Q data error detection

? Digital CLV spindle servo (built-in oversampling filter)

? 16-bit traverse counter

? Asymmetry correction 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

? VCO control mode

? Digital Out can be generated from the audio serial inputs.

? Supports three types of DA interface (48 bits/64 bits/32 bits)

? DSP, servo and DAC blocks support sleep mode.
