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.
I suggest please use of the adaptive bias features is shown in figure7.In some details see page12.http://www.analog.com/media/en/technical-documentation/data-sheets/AD8304.pdf
for AD8153 we'll verify and I'll get back to you.
