No output from ADV7511

Category: Hardware
Product Number: adv7511

Hello,

I'm currently using KC705 devboard ( which uses ADV7511) to generate a HDMI image to a monitor. I'm configuring using i2c and configuration looks to be successful as i can readback the data I'm sending, also I'm sending video timing and data signals to the transmitter but i don't see any output from ADV7511. can someone help me through this? Thankyou.

  • Hi,

    Do you have one of our evaluation boards for ADV7511? If yes, have you tested on our evaluation board and observed the same behavior?

    Please let us know, how do you configure the board either through scripts or through software driver?

    Do you have an HDMI analyzer to connect to that you can verify the ADV7511 output with?

    Thanks,

  • We don't have one of your eval boards. so KC705 board is a eval board from xilinx which has a kintex 7 series FPGA on it, I have made a I2c module on the FPGA and Iam configuring ADV7511 using the I2c module. when i configure using I2c i can see I2c transactions happening when i measure the sda and scl lines on a scope(both write and read transactions are occurring successfully) . 

    I dont have a HDMI analyser with me. Thankyou.
