Description
The CXD3003R 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 24× 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 24× 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 24× 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
• VCO control mode
