Is I2C Clock required in AD7992 Automatic Cycle Conversion mode?

Hi All,

We are using AD7992 analog to digital converter in our new

 

DWDM-PON based ONT design. The preferred mode of operation for the

 

converter is Mode 3 i.e. the Automatic cycle mode. Please confirm

 

whether the I2C clock is used for polling or reading the status of the A/D converter by the Soc.

 

Regards,

    Hi Mayank,

    Yes I2c clock or SCL is still required in Automatic mode. This is where your data is being clock out. The SDA
    line is where the communication between the master and slave and where the exchange of  data takes place. It tells that the transmission lines area ready to start or acknowledges the data from SDA. For Soc (system on
    chip), it is also used in.
