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.
