The DDS (Direct Digital Synthesizer) driver is a high resolution driver with extremely fast switching time (a few tens of nanoseconds) and is specially designed for use with acuosto-optic deflectors and shifters. The driver is a digital synthesizer based on monolithic IC circuits, and offers high frequency accuracy and stability.
