Re: ADV7281 I2C config

Hi Dave,

We tried below condition .Still we are unable to  get ACK from ADV7281.

1)      Power sequence provided as per datasheet . 3.3V first and  then 1.8V

2)      Then PWRDN signal is made HIGH followed by RESET

3)      We tried feeding external 28.6MHz clock also.  Still no response.

Is there any other way we can check.

What are the conditions for not getting ACK?

Thanks & Regards

Hi,

Any updates on below queries.

We are not getting ACK from ADV7281.

Is there any I2C sequence we need to follow?

Thanks & Regards

Hi Dave,

Do we need to write 0x0F thru I2C  ? Currently we are toggling PWRDWN pin thru GPIO.

Pls provide the I2C address and data sequence we need to follow?

Thanks & Regards
