3-12. Setting the Playback Speed for the CD-DSP and 1-bit DAC Blocks (in CLV-N mode)
(a) CD-DSP block
(b) 1-bit DAC block
In the CXD2548R, the following playback modes can be selected through different combinations of the
crystal, XTSL pin and the DSPB command of $9X.
Fs = 44.1kHz.
The operation speed for the DAC block is determined by the crystal and the MCSL command of $9X
regardless of the CD-DSP operating conditions noted above. This allows the playback modes for the DAC
and CD-DSP blocks to be set independently.
Fs = 44.1kHz.
1
Low power consumption mode. The CD-DSP processing speed is halved, allowing power consumption
to be reduced.
