SPDIF Input
SPDIF IN can operate at 44.1 KHz, 48 KHz, or 96 KHz, and implements internal Jack Sensing (Port
presence Detect).
A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to
directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs.
Status flags from the input stream are updated only after the entire valid block has been received (or
at least when all bits of a particular status flag have been received) to ensure that software does not
read an invalid mixture of old and new data.
