Is the AD/DA converter Cyclone 3 starter kit compatible

The Cyclone FPGAs can also handle CMOS or LVTTL inputs/outputs, so can be used with almost any ADC/DAC on the market. Giving an exact reference is difficult without knowing your requirement, but you can go on a manufacturer web site and do a parametric search to find the converter you need.

As long as its I/O is compatible with one of the I/O standards on the FPGA then you can use it. You may have to write some HDL yourself to interface with some ADC/DAC, depending on the interface type and your requirements. But this code to write isn't very complicated.
