I am searching for a DDS which has the feature of outputting a sign bit
with a software selectable phase shift.
This signal is used for a synchronous demodulator. The phase shifts in the sensor vary.
In the moment I am using a FPGA as a phase accumulator connected to a parallel DAC
LPF and so on. In the FPGA obviously I can do what I want.
I have to reduce the component count.
Frequency is fixed at 100KHz and so is amplitude.
