ADV7612-P Field Application issue

        The customer use it to implement outside display(HDMI/DVI Cable up to 2 meters-->ADV7612-->FPGA&MCU-->ADV7511-->Display), and their board card put in 1U case and those devices implement the huge display in he field .

        There's turn out that the ADV7162 does not output to FPGA& can't setted by external MCU. Work with their hardware engineer check the case's ground connect ok. Test the chip's voltage & the electrical parameters are OK. they change to use a new one in unwork board work well. 

         So is there any advice about to tracking the problem without do FA test? Thanks a lot.

  • Verify TMDS_CLK_x_RAW detects a clock

    Verify TMDSPLL_LCK_x_RAW is locked to incoming TMDS signal

    Verity V_LOCK_RAW is locked to video stream

    Use the correct configuration for the video format you are using.

    Why can't the 7612 be set by the MCU?  Ned to get I2C working first
