MAX9295 GMSL2 Dual CSI-2 Serializer with GMSL1 Compatibility
Analog Devices serializers enable full-duplex single-wire transmission of forward video and bidirectional control data

The Analog Devices MAX9295 serializer 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 15 m in length. In GMSL2 mode, the device operates at a fixed rate of 3 Gbps or 6 Gbps in the forward direction and 187.5 Mbps in the reverse direction. In GMSL1 mode, the MAX9295D can be paired with first-generation 3.12 Gbps or 1.5 Gbps GMSL1 deserializers or it can also operate up to 4.5 Gbps 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. The cable can be coaxial or shielded twisted pair (STP).

The MAX9295DHSDEVKIT# coax/HSD evaluation kit provides a reliable platform for evaluating the MAX9295 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 evaluation kit includes a simple-to-use Windows 10-compatible graphical user interface (GUI) for utilizing 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.
