CXD2598Q

CXD2598Q CD Digital Signal Processor with Built-in Digital Servo and DAC Description The CXD2598Q is a digital signal processor LSI for CD players. This LSI incorporates a digital servo, digital filter, 1-bit DAC and analog low-pass filter on a single chip. 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 4× continuous playback possible Allows relative rotational velocity readout Wide capture range playback mode Spindle rotational velocity following method Supports normal-speed 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 Sub-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 mete...
