Description
The CXD3029R is a digital signal processor LSI for CD players. This LSI incorporates a digital servo, high & bass boost, shock-proof memory controller, 1-bit DAC and analog low-pass filter.

Features
• All digital signal processing during playback is performed with a single chip
• Highly integrated mounting possible due to a built-in RAM

Digital Signal Processor (DSP) Block
• Supports CAV (Constant Angular Velocity) playback
• Frame jitter free
• 0.5× to 4× speed continuous playback possible
• Allows relative rotational velocity readout
• Wide capture range playback mode
• Spindle rotational velocity following method
• Supports 1× to 4× speed playback
• Supports variable pitch playback
• 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 4× speed playback
• Noise reduction during track jumps
• Auto zero-cross mute
• Subcode demodulation and subcode-Q data error detection
• Digital spindle servo
• 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
• CD TEXT data demodulation
• Digital Out can be generated from the audio serial input. (also supported after shock-proof and digital bass boost processing, subcode-Q addition function)
