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

Page 5: Functional Description
2.0 Functional description 2.1 Video path The APIX2 ADK Transmitter board offers video input from two independent HDMI/DVI sources. Both HDMI/DVI inputs are converted to parallel RGB data (24 Bit color depth). The parallel RGB signals are converted to 3-lane (18Bit) or 4-lane (24Bit) LVDS video streams which are fed directly into the INAP375T transmitter device. -
Page 6: Figure 2-3: Apix2 Adk Transmitter Control Path
User Manual Figure 2-3: APIX2 ADK Transmitter control path The microcontroller offers two independent I2C busses as well as one SPI bus. The I2S busses manage EDID information and control functions of both HDMI/DVI devices as well as control functions of the audio analog to digital converter. -
