I want to use AD91xx for I/Q timing delay adjustment measurement at f = 920MHz.
Input CLK frequency is 920MHz (or its multiply) and outputs are 920MHz I and Q phase.
I want to vary Q channel timing with AD91xx using the delay function that is built in the part to see the I and Q channel operation. The delay stepping of the Q channel should be
30.2 ps (this is 1/36 of 1/920MHz) or its integer division
and total delay variation should be more than 1087ns (this is 1/920MHz).
Please advise the best part that can be used for the application.
Also please advise its temp variations.
Awaiting your comments.
