Specific i2s cable for use with Sonnet Morpheus DAC & 3rd party DDC

Greetings,

I'm considering buying a Sonnet Morpheus. Reviewers seem to strongly favor using the i2s input on the Morpheus. I understand I can purchase a DDC (ex: Denafrips Hermes) to convert my music servers USB output into a i2s signal.

On their website Sonnet clearly tells the customer that their i2s input uses a non-conventional "pin configuration for the i2s input.

What I don't understand is the following: Must the i2s cable have its pin configuration custom configured for both the output (On the DDC device) as well as on the receiving end (i2s input on the Sonnet)?

More to the point- Does anyone know of a specific i2s cable that is compatible with the Sonnet Morpheus?

Thanks
