I have a requirement to produce a sinewave which is nominally 1MHz but that can be digitally changed in 1kHz steps up to +/-50kHz. It has to be stable to +/-100Hz between 50 & 125 degC. The digital update rate is << 1Hz.
Would the AD5930 or AD5932 device be suitable for this requirement? (I can't tell from the datasheets what units the delta_f register refers to)
