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)
