    I am looking for a design of a PCB and one prototype of a circuit which has two outputs, one with a sinewave and one with a cosine, i.e. phase shifted 90 degrees relative to the other output. The frequency should be programmable from 100 Hz to 1000 Hz, and the amplitude is not important, it can be a few volts. I am planning to implement this by controlling two DDS chips, e.g. AD 9835's ...
