General Description

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 singlewire

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).
