A frequency generator is a device or software that is capable of producing electrical signals at various frequencies. It is commonly used in electronics, telecommunications, scientific research, and other fields where precise frequency control is required.
The RTM876-660 is a 56 pin single-chip frequency generator.
Frequency generators can generate signals across a wide range of frequencies, from very low frequencies (in the hertz or millihertz range) to extremely high frequencies (in the gigahertz or terahertz range). They are often used for testing and calibrating electronic equipment, as well as for stimulating and measuring the response of circuits and systems.

There are different types of frequency generators available, including analog generators and digital generators. Analog frequency generators typically use oscillators or voltage-controlled oscillators (VCOs) to generate signals, while digital generators use direct digital synthesis (DDS) techniques to generate precise and stable frequencies.
