Overview
CXD3008Q CD Digital Signal Processor with Built-in Digital Servo For the availability of this product, please contact the sales office.
Description The CXD3008Q is a digital signal processor LSI for CD players.
This LSI incorporates a digital servo.
Features • All digital signal processings during playback are 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 1× to 4× playback variable pitch playback • 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× 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 output • Digital level meter, peak meter • Bilingual supported • VCO control mode • CD TEXT data demodulation • EFM playability reinforcement function Digital Servo (DSSP) Block • Microcomputer 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 function • Surf jump function supporting micro two-axis • Tracking filter: 6 stages Focus filter: 5 stages 80 pin QFP (Plastic) Applications CD players Structure Silicon gate CMOS IC Absolute Maximum Ratings • Supply volt...
