Overview
CXD3009Q CD Digital Signal Processor Description The CXD3009Q is a digital signal processor LSI for CD players and is equipped with built-in digital filters, zero detection circuit, 1-bit DAC, and analog low-pass filter on a single chip.
Features Digital Signal Processor (DSP) Block • Playback mode supporting CAV (Constant Angular Velocity) – Frame jitter-free – Allows 0.
5 to double-speed continuous playback – Allows relative rotational velocity readout – Supports external spindle control • Wide capture range playback mode – Spindle rotational velocity following method – Supports normal-speed and double-speed playback • 16K RAM • EFM data demodulation • Enhanced EFM frame sync protection • SEC strategy-based error correction • Subcode demodulation and Sub Q data error detection • Digital spindle servo • 16-bit traverse counter • Asymmetry compensation circuit • Serial bus-based CPU interface • Error correction monitor signals, etc.
are output from a new CPU interface.
• Servo auto sequencer • Digital audio interface output • Digital peak meter • CD-TEXT data demodulation Digital Filter, DAC, Analog Low-Pass Filter Block • DBB (Digital Bass Boost) • Supports double-speed playback • Digital de-emphasis • Digital attenuation function • Zero detection function • 8Fs oversampling digital filter Applications CD players Sony reserves the right to change products and specifications without prior notice.
