APIX2 ADK Transmitter Board (Rev2)
1.0 Introduction
The APIX2 ADK Transmitter board provides a variety of data inputs for digital video, audio and control data
processing to demonstrate all main functions of APIX2 INAP375T Transmitter devices. All board functions can
be controlled via a software GUI to an on-board microcontroller. Furthermore all functional pins of the
INAP375T device and board controls are accessible via pin headers
Features:
Two independent HDMI/ DVI ports for digital video input (24Bit or 18 Bit width color depth)
HSD or MX49 connector for APIX2 serial port
USB Interface to software GUI for easy control of all board functions
HDMI Audio input processing
Power over APIX support
