GMSL cameras grow popular for embedded vision projects

Product Insight

With the growing demand for embedded vision, higher data transmission rates and integrated processes, Rhonda Software has released GMSL2 Camera EVK to help accelerate time to market for custom camera development.


Gigabit Multimedia Serial Link (GMSL) cameras respond to the need for high-speed data transmission at a decent distance. Analog Devices introduced the GMSL interface and SerDes technology to create an alternative to standard image sensor interfaces. In common cameras image sensor is usually placed close to SoC (System On Chip) and connected directly over one of the standard interfaces (like MIPI CSI-2).



Here are some scenarios that require complex camera design


Camera sensors connected to an SoC, and that SoC has only one interface for connection

Camera sensors connected to an SoC, but located meters apart

Camera sensors and an SoC are located in different units

There is no place inside camera housing for an SoC

Remote LCD connected to an SoC


Vertical applications such as automotive, robotics, medical, and beyond



Analog Devices GMSL2 Main Features

Up to 6 Gbit/s

Up to 8MP resolution

Bandwidth suitable for 4K @ 30 fps

Up to 15 meters distance via single coax or STP cable

Almost 0 latency transmission of uncompressed data

Ability to multiplex additional metadata along with video

Provide enough power for camera and additional equipment such as IR projector


GMSL2 technology allows designing complex camera systems

GMSL Serializer converts parallel data streams into serial data streams of higher frequency. Then Deserializer converts the received serial data stream back into a parallel data stream.



GMSL integration for custom camera designs

Designing solutions with SerDes is challenging, including both Electronic Engineering and Software / Driver effort to ensure operational excellency.


Developing SerDes camera design from scratch would most likely result in a longer project duration, impacting both the schedule and budget.


With decades of experience in imaging solutions, sensor driver development, and GMSL SerDes components, Rhonda Software is now offering off-the-shelf GMSL2 solutions that can be used with a flexible level of customization.
