Oscillators are ubiquitous in electronics – you’ll find them in almost any electronic circuit, from the humble oscillator in a digital watch to the complex frequency synthesizers in a cellular phone. One such oscillator, the C3390-44.736, is used to generate high-frequency reference signals for a variety of applications.

The C3390-44.736 oscillator is designed to replace legacy single- and dual-tone oscillators when generating frequency-division multiplex (FDM) signals. The device operates from a single 5 V supply and works over a wide temperature range of -40°C to +85°C. It is designed to meet both commercial frequency stability requirements and hard-to-meet military frequency stability requirements.

The C3390-44.736 oscillator has an output frequency range of 833.3 kHz to 836.3 kHz and is designed to operate in two modes: low-power and high-power. High-power mode enables the oscillator to achieve a high output level of +13 dBm; in low-power mode, the output is +4 dBm. The device can be configured to output a single tone or two separate tones, depending on the application.

The C3390-44.736 has a highly stable and accurate frequency reference – its frequency accuracy is 0.5 ppm. This makes it ideal for applications that require accuracy, such as providing reference signals for frequency synthesizers or clock sources. The device also features low phase noise, which is important for minimizing signal interference in high-frequency applications.

The C3390-44.736 oscillator features fast start-up times, with an output reaching full amplitude in less than 1 ms. The device also has built-in thermal protection to keep it from being damaged during prolonged operation. In addition, the device features a power-down mode, which enables it to reduce power consumption when not in use.

The C3390-44.736 oscillator has a wide range of applications, including test and measurement equipment, point-to-point communication systems, frequency synthesizers, and mobile and satellite communication systems. The device is ideal for providing reliable, high-stability reference signals for these applications.

The working principle of the C3390-44.736 oscillator is based on a high-Q filter with a piezoelectric crystal as its resonator. The device is designed with careful selection of the piezoelectric material and the coil capacitance to ensure high-performance operation. The resonance frequency is determined by the capacitance and the inductance of the crystal. The oscillator’s output frequency is determined by the filter’s resonance frequency.

The C3390-44.736 oscillator is a highly versatile and accurate solution for frequency applications. Its wide frequency range, stability, and built-in protection features make it an ideal choice for many applications requiring reliable and high-performance frequency references. As such, it is a valuable addition to any engineer’s arsenal of components.
