Signbit phase shift

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.

Any idea?

 

Thanks
