The DS90UB926 interface module is a Grabber module supporting the
FPD-Link III Standard (Flat Panel Display Link).
It includes the DS90UB926Q receiver of Texas Instruments and a
DS90UB925Q transmitter for routing through in the (DS)
extended version.
The module is available as simple version (DS90UB926) without I2C
support as well as extended version (DS) with I2C support
and UUT supply.
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:
Backward compatible to FPD-Link II
HD Video resolution and Pixel clock frequency up to 85 MHz
I2C interface (only ex version)
UUT supply (only ex version)
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.
