The INAP375T MII interface module is a Generator module supporting
the APIX 2 standard (Automotive Pixel Link).
It includes the INAP375T transmitter of Inova Semiconductors.
Via an Ethernet Switch, the MII side band of APIX is coupled in or out.
The module has the following characteristics:
Downstream link with 3GBits/s band width
for Video transmission with up to 2591MBits/s
Upstream link for Data transmission with up to 187.5 MBits/s
HD Video resolution
and Pixel clock frequency up to 120 MHz
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 a “D4S20D-40ML5-Z” type connector of
Rosenberger, marked as “Output”. The Video signal is output via this
connector.
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 “Output” connector:

The electrical signal properties correspond to the APIX-Standard.
For UUT supply, a phantom supply is used. The Plus pole (
+
) is
applied to pins 1 and 3, the Minus pole (
–
) to pins 2 and 4.
