A Numerically Controlled Oscillator (NCO) is a digital circuit or algorithm that generates periodic waveforms with controllable frequencies. This makes it a versatile component in digital signal processing and communication systems.
NCOs are used in a wide variety of applications, including:
- Software Defined Radios (SDRs)
- Frequency synthesizers used in RF transceivers
- Digital Signal Processing (DSP)
- Test and Measurement Equipments
- Radar systems
- SONAR systems
The following table lists some NCO IC manufacturers:

NCOs and DDS Synthesizers
Direct Digital Synthesis (DDS) synthesizers use a Numerically Controlled Oscillator (NCO) to generate a waveform with a frequency determined by a tuning word. Hence, the NCO is often available as a built-in component of DDS ICs.
