I downloaded the attached file from this EngineerZone site.

According to this, I2C speed of AD9389B/9889B is up to 100kHz.


From page.5

>All earlier Tx only support up to 100kHz I2C

>AD9x89, AD9387, ADV7510, ADV7520, ADV7521


But, Hardware User's Guide of AD9389B/9889B describes that I2C speed is up to 400kHz.


Which is correct?


Best regards.
