Oscillators

An oscillator is a timed electronic signal generator. It typically produces an electronic signal of an exact frequency every time it is triggered. Oscillators are used in electronic instruments, such as clocks, radios, alarms, and digital watches, to maintain a stable frequency. They are also used in test equipment, radar, microwave systems, and telecommunications systems.

SIT1602BC-21-33N-60.000000G Application Field and Working Principle

The SIT1602BC-21-33N-60.000000G Oscillator is a combination of a voltage-controlled oscillator (VCO) and a frequency divider. It is capable of generating multi-frequency signals with ratios up to 15bits. The SIT1602BC-21-33N-60.000000G Oscillator can be used in a variety of applications including, but not limited to, telecommunications, instrumentation, broadcast, and consumer electronics.

The SIT1602BC-21-33N-60.000000G Oscillator is based on a circuit design that contains a voltage-controlled oscillator (VCO) which can be programmed to a frequency range of 24.75MHz to 48MHz. The frequency range is divided into three, four, or six divisions. Each division is composed of a voltage-controlled frequency divider (VCF), a phase-locked loop (PLL), and a crystal-controlled oscillator (OCXO) for stability.

The working principle of the SIT1602BC-21-33N-60.000000G Oscillator is based on the variation of the frequency of the VCO as the input voltage changes. The oscillator produces a fixed frequency whenever the applied voltage is constant. The frequency is determined by the ratio of the resistive and capacitive elements of the VCO.

The VCO is also used to divide the frequency by two and four-based on the division frequency setting. The PLL is used to phase-align the divided signals so that they are in sync with the reference signal. Finally, the OCXO is used to adjust the output frequency and to maintain its stability.

The SIT1602BC-21-33N-60.000000G Oscillator provides an ideal solution for applications that require repetitive multi-frequency signals with an extremely tight frequency stability. It can be used in a wide range of consumer electronics, instrumentation, and telecommunications applications.
