MAXIM MAX9296AGTM/V+T

The MAX9296A deserializer converts single or dual serial inputs to MIPI CSI-2 outputs. The device operates in either GMSL1 or GMSL2 mode. The MAX9296A also sends and receives side-channel data, enabling full-duplex transmis­ sion of forward path video and bidirectional control data over low-cost 50Ω coax or 100Ω STP cables to meet the GMSL2 or GMSL1 channel specification.

The GMSL2 links operate at a fixed rate of 3Gbps or 6Gbps in the forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, each serial link can be paired with 3.12Gbps or 1.5Gbps GMSL1 serializ­ ers or operate up to 4.5Gbps with GMSL2 serializers. The MAX9296A supports mixed GMSL2 and GMSL1 links. The serial inputs operate independently, allowing videos with different timings and resolutions 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.

Each four-lane CSI-2 port can be programmed to oper­ ate with any number of active data lanes. Each CSI-2 port supports 16 virtual channels and allows virtual chan­ nel and data type reassignment.

In GMSL1 and GMSL2 modes, the side-channel oper­ ates at 9.6kbps to 1Mbps in UART-to-UART mode, and 9.6kbps to 1Mbps in I2C-to-I²C mode with clock stretching. Using the side-channel, a μC residing on either end of the link can program serializer, deserializer, and peripheral device registers independent of video tim­ ing. In GMSL2 mode, two additional pass-through I²C or UART channels and a pass-through 50MHz SPI channel provides peripheral control.

The MAX9296A operates over the automotive tempera­ ture range of -40℃ to +105℃ and is AEC-Q100 qualified.
