CXD2510Q

CXD2510Q CD Digital Signal Processor Description The CXD2510Q is a digital signal processor LSI for CD players and is equipped with the following functions. Wide frame jitter margin (±28 frames) due to a builtin 32K RAM 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 Quadruple-speed, double-speed and variable pitch playback Noise reduction during track jumps Auto zero-cross mute Subcode demodulation and Sub Q data error correction Digital spindle servo (built-in oversampling filter) 16-bit traverse counter Asymmetry compensation circuit Serial bus-based CPU interface Error correction monitor signals are output from a new CPU interface. Servo auto sequencer Fine search which performs high-precision track jumps Digital audio interface output Digital level meter, peak meter Bilingual compatible Features All digital signals processed with a single chip during playback High-integrated mounting possible due to a built-in RAM Structure Silicon gate CMOS IC Absolute Maximum Ratings VDD Supply voltage –0.3 to +7.0 V Input voltage VI –0.3 to +7.0 V (VSS – 0.3V to VDD + 0.3V) Output voltage VO –0.3 to +7.0 V Storage temperature Tstg –40 to +125 °C Supply voltage difference Vss – AVss –0.3 to +0.3 V VDD – AVDD –0.3 to +0.3 V -L01 80 pin QFP (Plasti...
