The MAX9295D converts single- or dual-port MIPI CSI-2 data streams to GMSL2™ or GMSL1™ while sending and receiving control-channel data, enabling full-duplex single-wire transmission of forward video and bidirectional control data over cables in excess of 15m in length. In GMSL2 mode, the device operates at a fixed rate of 3Gbps or 6Gbps in the forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the MAX9295D can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1 deserializers or operate up to 4.5Gbps with GMSL2 deserializers configured for GMSL1 mode. Operation is specified over the automotive temperature range of -40°C to +105°C and the device is AEC-Q100 Grade 2 qualified. Cable can be coaxial or shielded twisted pair (STP).

Product Details

The MAX9295D Coax/HSD evaluation kit (EV kit) provides a reliable platform for evaluating Maxim’s MAX9295D GMSL2/GMSL1 CSI serializer using a standard FAKRA coax cable or HSD-STQ cable. The serializer device supports high-bandwidth, gigabit multimedia serial links (GMSL2/GMSL1) and offers 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.

For complete GMSL evaluation using a standard FAKRA coax cable or HSD-STQ cable, order the MAX9295D Coax/HSD EV kit along with a deserializer board.

For a detailed look at all GMSL2 features, including information on how to use the parts, refer to the GMSL2 User’s Guide.
