3.6. Phase Modulation

You can use the NCO IP core to add an optional phase modulator to your variation, allowing dynamic phase shifting of the NCO output waveforms. This option is particularly useful if you want an initial phase offset in the output sinusoid.

You can also use the option to implement efficient phase shift keying (PSK) modulators in which the input to the phase modulator varies according to a data stream. You set the resolution and pipeline level of the phase modulator in the NCO wizard. The input resolution must be greater than or equal to the specified angular precision.
