The MAX96716A converts dual GMSL2 serial inputs to MIPI CSI-2. It also transmits and receives control-channel data, enabling transmission of forward-path video and bidirectional control data. The GMSL2 link operates at a fixed rate of 6Gbps or 3Gbps in the forward direction, and 187.5Mbps in the reverse direction.

The GMSL™ inputs operate independently, allowing video with different timing and resolution to be received on each input.

Video data from both inputs can be aggregated for output on a single CSI-2 port or replicated on a second port for redundant processing.

The device and connected serializer are programmed through I2C or UART.

Operation is specified over the automotive temperature range of -40°C to +105°C and the device is AEC-Q100 qualified.

Data may be transmitted over low-cost 50Ω Coax or 100Ω STP cables that meet the GMSL2 channel specification. Contact the factory for the GMSL2 channel specification.

Product Details

The MAX96716 and MAX96792 evaluation kits (EV kits) provide a reliable platform for evaluating ADI devices MAX96716A, MAX96716F, and MAX96792A through the use of standard FAKRA coaxial cables or HMTD cable. These deserializer devices support high-bandwidth, gigabit, multimedia (GMSL) serial links and offer spread spectrum and full-duplex control channel features. The EV kit includes a simple-to-use Windows 10-compatible graphical user interface (GUI) for exercising device features.

In the following sections, the term deserializer refers to the MAX96716 and MAX96792A and any of the devices listed above. The term serializer refers to any GMSL2 serializer device, particularly the MAX96717. If using the MAX96792A in GMSL3 mode, the companion Serializer is MAX96793.

For complete GMSL2 or GMSL3 evaluation using a standard FAKRA coax cable or HMTD cable, order the MAX96716/MAX96792 COAX/STP EV kit along with a companion serializer board (MAX96717/MAX96793 COAX/STP EV kit is referenced in this document). For a detailed look at all GMSL2 features, including information on how to use the parts, refer to the GMSL2/GMSL3 User’s Guide (GMSL2/GMSL3_Users_Guide_vXX, found in Maxim’s GMSL customer portal folder)..
