The INAP375R 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.
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 APIX 1
Downstream link with 3GBits/s Band width
for Video reception with up to 2591 MBits/s
Upstream link for Data transmission with up to 187.5 MBits/s
HD Video resolution and Pixel clock frequency up to 120MHz
SPI interface
Data transmission is effected via two separated wire pairs for
Downstream and Upstream channel. Thereby, the different data, like
Video and SPI, use either only one channel or both channels.
The Video signal is always transferred 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 following table shows the assignment of the “Input” connector:
Pin

SD_UP_OUT_N
Serial data Upstream negative
2
SD_DOWN_IN_P
Serial data Downstream positive
3
SD_UP_OUT_P
Serial data Upstream positive
4
SD_DOWN_IN_N
