ADSP-SC58x/2158x SPDIF-RX feature list: What's new?

The ADSP-SC58x/2158x processors have new SPDIF receiver design. The features are:

1. It supports sampling rates from 24KHZ to 96KHZ

2. It can detect Audio word length from channel status bits as specified by IEC 60958-3

3. It can detect compression type by using burst info as specified by IEC 61937-2

4. It can detect whether compression type is DTS or AC3.

5. It doesn't support interrupt for CRC error and parity error and emphasized audio( These are supported in ADSP-214xx).

6.The SCDF mode which was supported in ADSP-214xx is not available in new design

    Hi Nithin,

    Yes, your understanding is correct. ADSP-SC58x processor requires SPDIF signal (Biphase stream) to be of 0 to 3.3v signal levels. We need LVDS transceivers to convert Standard coaxial line voltage levels (500mv) to 3.3V of the processor. It's similar to how we use UART transceivers for UART to convert 3.3v to physical line standards.

    Thanks,
