LC78616PE
CD data output function
Two modes can be available for CD data output.
(1) Normal mode
In this mode, output signals are LRCK, BCK and DATA. CLV or Jitter-Free(VCEC) playback is supported.
When CDDA playback, depending on the specification of Audio DAC, FS384 clock output is also available .
(2) Slave mode
In ths mode, output signal is DATA, and input signals are LRCK, BCK. The DATA output is synchronized to
input clocks (LRCK,BCK).
It is enable to output CD data synchronized to Audio DAC without connecting FS384clock.
This mode is only available for CD normal playback, and LRCK frequency must be 44.1kHz.
