1 / 115 page  Description The CXD2597Q is a digital signal processor LSI for CD players. This LSI incorporates a digital servo, digital filter, 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 • 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 • 16K RAM • EFM data demodulation • Enhanced EFM frame sync signal protection • SEC strategy-based error correction • 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 • Digital audio interface outputs • Digital level meter, peak meter • CD TEXT data demodulation 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 functions Digital Filter, DAC and Analog Low-Pass Filter Blocks • DBB (digital bass boost) function • Double-speed playback supported • Digital de-emphasis • Digital attenuation • Zero detection function • 8Fs oversampling digital filter • S/N: 100dB or more (master clock: 384Fs, typ.) Logical value: 109dB • THD + N: 0.007% or less (master clock: 384Fs, typ.) • Rejection band attenuation: –60dB or less Applications CD players Structure Silicon gate CMOS IC Absolute Maximum Ratings • Supply voltage VDD –0.3 to +7.0 V • Input voltage VI –0.3 to +7.0 V (VSS – 0.3V to VDD + 0.3) • 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 Note) AVDD includes XVDD and AVSS includes XVSS. Recommended Operating Conditions • Supply voltage VDD +2.7 to +5.5 V • Operating temperature Topr –20 to +75 °C Note) The VDD for the CXD2597Q varies according to the playback speed selection. – 1 – CXD2597Q E97Z35-PS CD Digital Signal Processor with Built-in Digital Servo and DAC Sony reserves the right to change products and specifications without prior notice.
