Numerically Controlled Oscillator NCO IC Manufacturers

A Numerically Controlled Oscillator is a digital circuit or algorithm that generates periodic waveforms with controllable frequencies, making it a versatile component in digital signal processing and communication systems.

NCOs are used for wide variety of applications which include Software Defined Radios (SDRs), Frequency synthesizer used in RF transceivers, Digital Signal Processing (DSP), Test and Measurement Equipments, Radar systems, SONAR systems and so on. Following table mentions NCO IC manufacturers.

Direct Digital Synthesis (DDS) synthesizer uses a Numerically Controlled Oscillator (NCO) to generate a waveform with a frequency determined by a tuning word. Hence often NCO is available as built-in component of the DDS ICs. Refer NCO >> for more information on NCO working principle, benefits and applications.
