1 / 147 page  CXD2598Q CD Digital Signal Processor with Built-in Digital Servo and DAC 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 built- in 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 compatible • VCO control mode • 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 • 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 attenuation • 8fs oversampling digital filter • Adoption of tertiary ∆∑ noise shaper • 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 • Double-speed playback supported 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 + 0.3V) • Output voltage VO –0.3 to +7.0 V (Vss – 0.3V to VDD + 0.3V) • 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 CXD2598Q varies according to the playback speed selection. I/O Pin Capacitance • Input capacitance CI 11 (Max.) pF • Output capacitance CO 11 (Max.) pF • I/O capacitance CI/O 11 (Max.) pF Note) Measurement conditions VDD = VI = 0V fM = 1MHz – 1 – E97Y14-PS Sony reserves the right to change products and specifications without prior notice.
