Questions on model AD91xx

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.
