Overview
CXD3000R CD Digital Signal Processor with Built-in Digital Servo and DAC For the availability of this product, please contact the sales office.
Description The CXD3000R 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 16× 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 16× 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 16× 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 Digital Servo (DSSP) Block • Microcomputer software-based flexible servo control • Offset cancel function for servo error signal • Auto gain control function for servo loop • E:F balance, focus bias adjustment function • Surf jump function supporting micro two-axis Digital Filter and DAC Blocks • Digital de-emphasis • Digital attenuation • 4Fs oversampling filter • Adoption of a secondary ∆∑ noise shaper • S...
