In Coax mode, terminate the SION trace with an AC coupling capacitor and 50Ω resistor to ground. In STP mode, ensure length matching and consistent coupling distance between traces.

Many of Maxim’s GMSL parts include line-fault circuitry to detect a short to ground, short to the battery, and a disconnected cable. This application note discusses how to adapt GMSL line-fault circuitry for power over coax (PoC) and offers a solution to protect against overvoltage and overcurrent conditions.

GMSL：Gigabit Multimedia Serial Link是Maxim公司 (maximintegrated.com)推出的一种高速串行接口，适用于视频、音频和控制信号的传输，使用50Ω同轴电缆或100Ω屏蔽双绞线电缆，传输距离可达15m或更长。

GMSL2 devices support both 50Ω coaxial and 100Ω differential pair cables (example, STP, SPP, STQ) that meet the GMSL2 Channel Specification. Refer to the GMSL2 Hardware Design Guide for more details on supported cables and connectors.

2023年8月14日 · GMSL支持Power Over Coax（同轴供电）功能，要实现此功能，同轴内导体频谱被分为三个频段：供电、反向信道数据、前向信道数据，如下图所示。 通过滤波将确切的频段分配至对应的电路。 数据通道为AC耦合，通过收发机输入端串联电容实现。

2023年6月6日 · 吉比特多媒体串行链路，Gigabit Multimedia Serial Links，缩写为GMSL，是Maxim公司 (现在被 ADI 收购了)推出的一种高速串行接口，适用于视频、音频和控制信号的传输，使用50Ω同轴电缆或100Ω屏蔽双绞线电缆，传输距离可达15m或更长。 GMSL技术的特点是将并行数据转换成串行数据发送，在接收端将串行数据解码为并行数据，其优势有：高速率、远距离、抗干扰性强等。 目前基于GMSL架构的通信协议最高可实现单通道12Gbps的速率（GMSL3） …

Gigabit Multimedia Serial Link™ (GMSL) cameras use the GMSL and GMSL2 technology to carry high speed video, bidirectional control data, and power over a single coaxial cable.

2023年4月1日 · It delivers digital video streams, bidirectional control data, status reporting, as well as touch, haptics, and audio data over a single, small-diameter 50 Ω coaxial or 100 Ω shielded twisted pair (STP) cable. GMSL is known as a robust and power-efficient video link in the automotive industry.

GMSL的Serializer芯片在Coax线缆的应用中，OUT-端需要外接50ohm的终端电阻，那在STP线缆的应用中，是否也需要相同的配置？

GMSL1 devices use Maxim’s proprietary Gigabit Multimedia Serial Link (GMSL1) technology to transport high-speed serialized data over coax or shielded twisted-pair cable for automotive camera and display applications.
