The HSD to SMA Cable connection combination makes sense in certain applications, but its usage is limited. HSD to SMA with RG316 RF Coaxial Cable is not a standard combination.  

Possible Uses, Appropriate applications  : 

1. For Testing or Conversion   

In lab or testing environments, SMA connectors can be used to connect test equipment such as spectrum analyzers or oscilloscopes, and then connected to the automotive HSD interface via an adapter for signal analysis.

For example, during debugging of camera systems, radar, or high-frequency signal paths.

2. Interfacing with Certain High-Frequency Modules : 

Some manufacturers may produce HSD-to-SMA cables or adapters for compatibility purposes, allowing the HSD side to connect to the vehicle system and the SMA side to interface with RF modules or antennas.

Incorrect or Not Recommended Uses :  Direct Transmission of Video or Data  

HSD is a differential pair connector used for high-speed data transmission e.g., LVDS video or Ethernet, whereas SMA is a 50Ω single-ended RF signal connector. The signal structures are fundamentally different and cannot be directly substituted or interconnected.
