DDS Compiler v4.0 - How to generate a variable frequency square wave using DDS?

Description

Are there any example designs or recommended methods to generate a square wave (For example, 1-100Khz), using the DDS compiler?

Solution

No, DDS is primarily designed for sine, cosine and phase generation.

Its applications include phase and frequency modulation.

 

A variable frequency Square can be generated using a level threshold approach by taking the MSB of phase_out.

However, this method is not tested by Xilinx and the precision of the output is not assured.
