Gigabit Multimedia Serial Link
Gigabit Multimedia Serial Link, commonly referred to as GMSL, is a serial link technology that is used for video distribution in cars. It was developed by Maxim Integrated. Maxim Integrated was acquired by Analog Devices in 2021. GMSL is an asymmetric, full duplex SerDes technology - which means that it transports data at a high rate in the downlink (or forward) direction, while simultaneously transporting a lower data rate in the uplink (or reverse) direction. It transports power, bidirectional control data, Ethernet, bidirectional audio and multiple streams of unidirectional video simultaneously over a single coaxial cable or shielded twisted pair cable.
