CXD3021R

CXD3021R CD Digital Signal Processor with Built-in Digital Servo and DAC For the availability of this product, please contact the sales office. 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 ...
