SPDIF Input
output drivers. Please reference the HD Audio Universal Jack Application Note on the IDT Extranet
for more information.
SPDIF IN can operate at 44.1 KHz, 48 KHz or 96 KHz and implements internal Jack Detect.
A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to
accept consumer SPDIF voltage levels directly eliminates the need for costly external receiver ICs.
Advanced features such as record slot select and SPDIF_IN routing to the DAC allows for simulta-
neous record and play.
