i'm thinking the system where IF frequency translation occurs using one Dual DAC chip.
and the following is what i'm thinking.
input 1 : 100M update rate, 25M IF real data ---> port 1 of Dual DAC ---> 75M IF output
input 2 : 100M update rate, 25M IF real data ---> port 2 of Dual DAC ---> 75M IF output
is it possible ?
i'm thinking i need to use NCO and multipling to IF data but in DAC datasheet there's only option of
real mixer/ complex mixer. and i'm gessing both cases use 2 data set like i data and q data.
are there another way of multipling 1 data (IF data) with NCO clock ?
and i'm thinking of AD9788/AD9125 DAC chip.
