The MAX9272 interface module is a Grabber module supporting the
GMSL (Gigabit Multimedia Serial Link) standard.
It includes a MAX9272 receiver of Maxim Integrated and a MAX9273
transmitter for routing through.
The Module has a second connection and appropriate circuitry,
enabling not only signal receiving, but also routing through.
By this, the Grabber module can be inserted into an existing system of
transmitter and receiver without changing the system itself.
The module has the following characteristics:
1.5 GBits/s GMSL
28 bits transmission (colors and control signals)
Pixel clock frequency up to 100 MHz
UART or I2C interface
UUT supply (only for Coax version)
Two connection versions – STP and Coax
In the “STP” version (Shielded Twisted Pair), the module includes two
“D4S20D-40ML5-Z” type connectors of Rosenberger, whereof the
“Input” connector receives the signals, while the “Output” connector
routes the signals through.
The following table shows the assignment of the STP “Input”
connector:

In the “Coax” version, the module includes two „59S21B-40MT5“
connectors of Rosenberger, whereof the “Input” connector receives
the signals, while the “Output” connector routes the signals through.

For UUT supply via Coax, a phantom supply is used. The Plus pole (

is applied to the inner pin, the Minus pole (

The electrical signal properties correspond to the
GMSL standard.
