CXD3048R

CXD3048R CD Digital Signal Processor with Built-in Digital Servo + Shock-proof Memory Controller + Digital High & Bass Boost Description The CXD3048R 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 D...
