The MAX96792A converts dual GMSL™ 3/2 serial inputs to MIPI CSI-2. It receives forward-channel video data, and simultaneously receives and transmits bidirectional control channel data over Coaxial or Shielded-Twisted Pair (STP) cables. The PAM-4 based GMSL3 serial link operates at 12Gbps in the forward direction and 187.5Mbps in reverse direction. The MAX96792A is backward compatible with GMSL2 and can be paired with 6Gbps or 3Gbps GMSL2 serializers. The GMSL inputs operate independently, allowing video with different timing and resolution to be received on each input. The two GMSL links can also have different data rates. Video data from both inputs can be aggregated for output on a single CSI-2 port and can be replicated on a second output port for redundant processing. The device is configured using an I2C or UART interface. GPIO, I2C, UART, and SPI tunnels are available.

The device is AEC-Q100 qualified.

Data can be transmitted over low-cost 50Ω Coax or 100Ω STP cables that meet the GMSL3 or GMSL2 channel specification. See Table 1 in data sheet for typical maximum cable lengths. Contact the factory for the GMSL3 or GMSL2 channel specifications.

Product Details

The MAX96716 and MAX96792 evaluation kits (EV kits) provide a reliable platform for evaluating ADI devices MAX96716A, MAX96716F, and MAX96792A through the use of standard FAKRA coaxial cables or HMTD cable. These deserializer devices support high-bandwidth, gigabit, multimedia (GMSL) serial links and offer spread spectrum and full-duplex control channel features. The EV kit includes a simple-to-use Windows 10-compatible graphical user interface (GUI) for exercising device features.

In the following sections, the term deserializer refers to the MAX96716 and MAX96792A and any of the devices listed above. The term serializer refers to any GMSL2 serializer device, particularly the MAX96717. If using the MAX96792A in GMSL3 mode, the companion Serializer is MAX96793.

For complete GMSL2 or GMSL3 evaluation using a standard FAKRA coax cable or HMTD cable, order the MAX96716/MAX96792 COAX/STP EV kit along with a companion serializer board (MAX96717/MAX96793 COAX/STP EV kit is referenced in this document). For a detailed look at all GMSL2 features, including information on how to use the parts, refer to the GMSL2/GMSL3 User’s Guide (GMSL2/GMSL3_Users_Guide_vXX, found in Maxim’s GMSL customer portal folder)..
