Coaxial

Coaxial​

The transmission is a digital signal, the protocol is SPDIF, and the transmission medium is a cable, and different manufacturers may use different interfaces. For example: Type-C, RCA, 3.5mm interface, etc.

Coaxial (Type-C -> RCA)​

One end is the Typc-C interface, and the other end is the RCA interface.

On the existing USB TypeC interface, SUB1/SUB2 (pins A8/B8 below) on the Type-C interface are used to transmit the SPDIF signal. Since SUB1/SBU2 is used, other functions on the Type-C interface are still normal.

The main products that use Type-C interface for coaxial interfaces are as follows:

Coaxial (3.5mm -> RCA)​

One end is a 3.5mm two-stage (TS) interface, and the other end is an RCA interface.

The main products that use 3.5mm interfaces for coaxial interfaces are the following products:

  • Hiby HC10
