ADV7182 - A customer is following the correct power sequencing recommended in the datasheet however they are not able to communicate with the chip through I2C
The following image shows a snapshot of the power up sequence, the order is as follows:
- The 3.3v supply starts
- The 1.8v supply starts
- The power-down pin released
- Finally the reset line
However the chip is not acknowledging the address 0x40 (ALSB pulled down)
Do you have any recommendations?
