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
