Arduino DDS Sinewave Generator

Is it possible to have a three phase sine wave with this generator ?
I would like to generate a 10 kHz to idealy 18 kHz three phase wave.
Does miro-Hertz precision will pertain with this change ?

ten Khz is anyway a problem, the atmega is to slw for that. using a dedicated DDS chip would be a solution
maybe some manufactor has a 3 phase version.
