We planed to use ADC AD9269 16 bit ADC 80MSPS and DAC AD9747 16bit.
These two devices have two parallel data buses one for each channel.
- AD9747 states that in single port mode I & Q data can be placed on Port1 data bus. I am interfacing this DAC to ADSP21366 (16 parallel data bus), with what reference (Clock or DCO) should I post data. Can you send interface details for the above requirement.
- In 9269 interleaved mode, channel A & B data are valid with reference to DCO, but on which data bus and how to select it.
- In these ADC and DAC data sheets bypass capacitor values are not mentioned. How to derive these inputs.
