Oscillators

A oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clock generators to complex digital devices like radio-frequency and pulse oscillators.

The CE3292-64.000 oscillator is a voltage-controlled oscillator (VCO) from Cherry Electronics designed for use in systems that require a constant high-frequency RF signal source. This type of oscillator is specifically designed to provide stable and reliable signals at 64 MHz across a wide temperature range.

Application Field

The CE3292-64.000 oscillator is a high-speed, frequency-stabilized VCO that works as a frequency source of up to 64 MHz. It is widely used in a variety of applications such as satellite receivers, military systems, cellular communications, RF transceivers, and Global Positioning Systems (GPS). It also finds its uses in radar and navigation systems, directional antenna systems, fiber-optic networks, modems, and data acquisition systems.

Working Principle

The CE3292-64.000 oscillator operates on a pulse domain principle, whereby a small-valued series of pulses is generated to form an oscillating triangle waveform as the output. The resulting triangle waveform is then used to produce an accurate 64 MHz sine wave.

The frequency of the sine wave output is controlled by an external voltage controller. This voltage is then amplified, filtered, and sampled to produce a series of pulses whose length is proportional to the voltage applied. The pulses are then used to drive an oscillator built from an inverter containing feedback, and the resulting triangle wave is sliced to create the 64 MHz sine wave output.

The frequency of the sine wave can also be adjusted using the device\'s integrated digital control. This control can be used to adjust the frequency over a range of -500 to +500 ppm and can provide a total amplitude accuracy of ±1%.

The CE3292-64.000 oscillator is designed to operate over a wide range of temperatures and supply voltages, from -40°C to +85°C and from 4.0V to 5.5V, respectively. This ensures consistent operation in high-temperature and high-humidity environments. The device also meets the shock and vibration test standards specified by the Automotive Electronics Council (AEC).

The CE3292-64.000 oscillator is an efficient and reliable device that is capable of providing stable and accurate 64 MHz sine wave outputs over a wide range of environmental conditions. It is ideal for applications ranging from satellite receiving, military systems, cellular communications, RF transceivers, and GPS, to radar and navigation systems, directional antenna systems, modems, and data acquisition systems.
