Analog Devices Inc. MAX9295D GMSL2 Dual CSI-2 Serializers

Analog Devices MAX9295D GMSL2 Dual CSI-2 Serializers convert MIPI CSI-2 data streams to GMSL2™ or GMSL1™ formats. The Analog Devices MAX9295D supports single- or dual-port configurations. It facilitates full-duplex video transmission and bidirectional control data over cables longer than 15m. In GMSL2 mode, it operates at 3Gbps or 6Gbps forward and 187.5Mbps reverse speeds. GMSL1 mode pairs with 3.12Gbps or 1.5Gbps GMSL1 deserializers or operates up to 4.5Gbps with GMSL2 deserializers configured for GMSL1. The device is AEC-Q100 Grade 2 qualified for automotive use across -40°C to +105°C, supporting coaxial or shielded twisted pair (STP) cables.
