CXD2598Q Datasheet | Sony Semiconductor Solutions

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 meter - Bilingual patible - VCO control mode - CD TEXT data demodulation Digital Servo (DSSP) Block - Microputer software-based flexible servo control - Offset cancel function for servo error signal - Auto gain control function for servo loop - E:F balance, focus bias adjustment functions - Surf jump function supporting micro two-axis - Tracking filter: 6 stages Focus filter: 5 stages Digital Filter, DAC and Analog Low-Pass Filter Blocks - DBB (digital bass boost) function - Digital de-emphasis - Digital...
