We are using ADV7343  and I2C control of this is done using DM8168,we have configured the input of ADV7343 to take 16 bit ycbcr input from FPGA.The problem is we are not able to detect the I2C when we give I2C detect command,other I2C devices on the same i2C lines are responding.

We are giving VDDIO as 3.3V and VDD 1.8V. The sequence is proper with 1.8V coming after 80mSec.

We tried pulling ALSB pin low and high but to no effect.Can any one help with this issue.Any one faced similar issues.
