General Description

The MAX96717 GMSL™ serializer receives video on an MIPI CSI-2 interface and outputs it on a GMSL2 serial link transceiver. Simultaneously, it sends and receives bidirectional control channel data across the same GMSL2 link. GMSL2 data can be transported over Coaxial or Shielded-Twisted Pair (STP) cables. It operates at a fixed rate of 3Gbps or 6Gbps in the forward direction, and 187.5Mbps in the reverse direction. The device is programmed through a local I2C/UART interface or across the link from a matching deserializer. The MAX96717 includes two I2C/UART pass-through channels, flexible GPIO, SPI tunnel, a built-in ADC, temperature sensor, and an extensive set of diagnostics for functional safety. Operation is specified over the automotive temperature range of -40°C to +105°C and the device is AEC-Q100 Grade 2 qualified.

Data can be transmitted over low-cost 50Ω Coax or 100Ω STP cables that meet the GMSL2 channel specification. Table 1 provides guidance to typical maximum lengths of commonly used automotive cables. Contact the factory for the GMSL2 channel specification.
