Note: Peak to peak jitter is currently limited to less than 4.5nS (half of the internal master clock cycle)
which does not meet the IEC-60958-3 0.05UI requirement at 192KHz.
The two SPDIF output converters can not be aligned in phase with the DACs. Even when attached
to the same stream, the two SPDIF output converters may be misaligned with respect to their frame
boundaries.
Per the HDA015-B ECR, the SPDIF outputs support the ability to provide clocking information even
when no stream is selected for the converter, or when in a low power state. Also, as stated in the
ECR, the SPDIF output ports support port presence detect.
SPDIF Outputs are outlined in tables below.
