Figure 4. Relation Between Audio Data Output Timing and UNLOCK Flag Timing
unlock flag minimum pulse width time
CASE-A when PLL is unlocked
In the PLL clock operation mode, when PLL goes to unlock by a disconnected S/PDIF signal, the UNLOCK flag
pin indicates high and the audio data output DOUT becomes low (MUTE). The MUTE period, t
(UNL)
, is a
minimum of 200 ms. In this period, SCKO, BCKO, and LRCKO frequencies hold the latest tracked frequency.
If the S/PDIF signal is connected again in this unlock period, the bit rate is changed to the incoming signal
frequency, after at least 1 ms (before the UNLOCK flag becomes low). CKTRNS indicates the validity of SCKO.
When CKTRNS is high, the frequency of SCKO, BCKO, and LRCKO is in transition.
