Introduction to Programmable Oscillators

A programmable oscillator is an electronic oscillator circuit with built-in digital logic that can generate a range of signals with custom frequencies and shapes. Unlike conventional oscillators with a fixed frequency, programmable oscillators allow programming the output frequency using digital data that can be generated by a digital processor, microcontroller, or other digital instrument.Programmable oscillators can be used in a variety of applications such as frequency measurement, frequency sweeping, communications, timing, and delay generation. They are commonly used in communications, industrial automation, and biomedical applications. They are cost effective, reliable, and easy to use.

SIT1602BIE8-33S Programmable Oscillator Operating Principle

The SIT1602BIE8-33S programmable oscillator is a single-chip programmable oscillator for frequency applications up to 33 MHz. It is a low-power, low-voltage circuit, with a power consumption of 5 mW and a supply voltage of 3.3V.The SIT1602BIE8-33S programmable oscillator consists of a voltage controlled oscillator (VCO) and a programmable loop filter. The VCO generates a sinusoidal waveform with a frequency from 10 kHz to 33 MHz, and the loop filter determines the frequency of the output waveform by adjusting a slowly changing feedback parameter.The SIT1602BIE8-33S programmable oscillator can be programmed by either digital or analog inputs. With digital input, the external control input is synchronized by the clock input. All programmable settings, including frequency, ramp time, and gain, can be programmed. With analog input, frequency and ramp time can be programmed.
