Description
The CXD2548R 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
• All digital signal processing during playback is performed with a single chip
• Highly integrated mounting possible due to a builtin RAM
Digital Signal Processor (DSP) Block
• Playback mode which supports CAV (Constant Angular Velocity)
• Frame jitter free
• 0.5 × to 2.5 × continuous playback possible
• Allows relative rotational velocity readout
• Supports spindle external control
• Wide capture range playback mode
• Spindle rotational velocity following method
• Supports normal-speed, double-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 compensation 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
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
Digital Filter, DAC and Analog Low-Pass Filter Blocks
• Digital de-emphasis
• Digital attenuation
• Zero detection function
• 8Fs oversampling digital filter
• S/N: 100dB or more (master clock: 384Fs, typ.)
• THD + N: 0.007 or more (master clock: 384Fs, typ.)
• Rejection band attenuation: –60dB or more
