CXD3003R
CD Digital Signal Processor with Built-in Digital Servo and DAC
For the availability of this product, please contact the sales office.
Description
The CXD3003R is a digital signal processor LSI for
CD players. This LSI incorporates a digital servo,
digital filter and 1-bit DAC.
Features
鈥?/div>
All digital signal processing during playback is
performed with a single chip
鈥?/div>
Highly integrated mounting possible due to a built-
in RAM
Digital Signal Processor (DSP) Block
鈥?/div>
Playback mode supporting CAV (Constant Angular
Velocity)
鈥?/div>
Frame jitter free
鈥?/div>
0.5脳 to 24脳 continuous playback possible with a
low external clock
鈥?/div>
Allows relative rotational velocity readout
鈥?/div>
Wide capture range playback mode
鈥?/div>
Spindle rotational velocity following method
鈥?/div>
Supports 1脳 to 24脳 playback by switching the built-
in VCO
鈥?/div>
The bit clock, which strobes the EFM signal, is
generated by the digital PLL
鈥?/div>
EFM data demodulation
鈥?/div>
Enhanced EFM frame sync signal protection
鈥?/div>
Refined super strategy-based powerful error
correction
C1: double correction, C2: quadruple correction
Supported during 24脳 playback
鈥?/div>
Noise reduction during track jumps
鈥?/div>
Auto zero-cross mute
鈥?/div>
Subcode demodulation and Sub Q data error
detection
鈥?/div>
Digital spindle servo (built-in oversampling filter)
鈥?/div>
16-bit traverse counter
鈥?/div>
Asymmetry compensation circuit
鈥?/div>
CPU interface on serial bus
鈥?/div>
Error correction monitor signal, etc. output from a
new CPU interface
鈥?/div>
Servo auto sequencer
鈥?/div>
Fine search performs track jumps with high
accuracy
鈥?/div>
Digital audio interface outputs
鈥?/div>
