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.

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.

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。

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。

The GMSL link provides camera power, camera control, fault reporting and video transport across a single, coaxial cable. ADAS systems are considered safety-critical systems, and typically have an Automotive Safety Integrity Level (ASIL) rating, specified according to the ISO 26262 standard.

2024年3月26日 · GMSL 英文全称为 Gigabit Multimedia Serial Link ，是美信推出的一种针对车用的串行传输接口标准，用来支持未来 ADAS 和信息娱乐系统要求的宽带、互联复杂度和数据完整性的要求。

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.

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.
