The INAP375R MII interface module is a Grabber module supporting
the APIX 2 standard (Automotive Pixel Link).
It includes the INAP375R receiver of Inova Semiconductors and an
INAP375T transmitter for routing through.
Via an Ethernet Switch, the MII side band of APIX is coupled in or out.
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:
Downstream link with 3GBits/s band width
for Video reception with up to 2591MBits/s
Upstream link for Data transmission with up to 187.5MBits/s
HD Video resolution
and Pixel clock frequency up to 120MHz
MII interface for the transmission of Ethernet data
UUT supply
The transmission of the APIX data is effected via two separated line
pairs for Downstream and Upstream. The different channels like Video
and MII are using either one channel or both channels.
The Video signal is always transmitted via the Downstream.
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 also
existing RJ45 socket can be connected via Ethernet with a Personal
computer for handling the MII side band.
The following table shows the assignment of the “Input” connector:

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