Programmable Oscillators - SG-9101CE-C05PGDCB application field and working principle

Oscillators are electrical circuits or components used for generating a continuous and reliable high frequency sine wave signals, or alternatively square wave or triangular wave signals which can be adjustable as per user requirements. Oscillators are widely used in wireless communication application, instrumentation, sensors, medical devices and many other industry designs.

Programmable oscillators are those oscillators whose frequency output can be altered, however they are more complex than ordinary oscillators. When the frequency of a programmable oscillator is designed and configured, it stays at the same frequency during operation. The output frequency of a programmable oscillator can be changed only if the programming pins\' voltage level changes.Programmable oscillators typically incorporate programmable logic circuits, such as a read-only-memory (ROM), look-up table, or microprocessor, to modify the output frequency, if input changes.

SG-9101CE-C05PGDCB application field and working principle

The SG-9101CE-C05PGDCB is a programmable oscillator manufactured by Silicone Laboratories, a Texas based semiconductor company. SG-9101CE-C05PGDCB programmable oscillator is a widely used device in radio frequency, microwave, medical and other high performance applications.
