SBAS519 – SEPTEMBER 2010

Channel status, user data, and valid audio data from the S/PDIF stream can be found in various registers or

routed to MPIO pins. In addition, the block start signal can be routed to an I/O pin, so that any postprocessing

DSP can be informed of the start of a frame for decoding data and so forth.

The DIR module in the DIX9211 complies with these digital audio I/F standards:

•

S/PDIF

•

IEC60958 (formerly IEC958)

•

JEITA CPR-1205 (formerly EIAJ CP-1201/340)

•

AES3

•

EBU Tech 3250 (also known as AES/EBU)

In addition, the DIR Module within the DIX9211 also meets and exceeds jitter tolerance specifications defined by

IEC60958-3 for sampling frequencies between 28 kHz and 216 kHz.

Digital Audio Interface Transmitter (DIT)

The DIT (S/PDIF transmitter) is a relatively simple module. The DIT integrated in the DIX9211 is able to transmit

control status and user bits in the data stream, as well as standard 24-bit audio. Channel status, user data, and

Audio Valid bits in the stream are configured on incoming MPIO pins.

The DIT complies with the following audio standards:

•

S/PDIF

•

IEC60958 (formerly IEC958)

•

JEITA CPR-1205 (formerly EIAJ CP-1201/340)

•

AES3

•

EBU Tech 3250 (also known as AES/EBU)
