The CXD3021R is a digital signal processor LSI for CD players. This LSI incorporates a digital servo, digital filter and 1-bit DAC.
CXD3021R Key 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 supporting CAV (Constant Angular Velocity)
- Frame jitter free
- 0.5× to 32× continuous playback possible with a low external clock
- Allows relative rotational velocity readout
- Wide capture range playback mode
- Spindle rotational velocity following method
- Supports 1× to 32× playback by switching the built-in VCO
- The bit clock, which strobes the EFM signal, is generated by the digital PLL
