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)
