Oscillators: CE3392-64.000 Application Fields and Working Principles

The CE3392-64.000 is a high precision oscillator with a wide range of applications fields, including Quartz Crystal Oscillators (QCOs), Voltage Controlled Oscillators (VCOs) and Phase-Locked Loop circuits (PLLs). In addition to its use in the above circuits, this device could also be used for general time base and frequency control applications. The CE3392-64.000 is a high performance, low jitter oscillator with a frequency range of 8kHz to 36MHz. The precision of this oscillator is outstanding and is capable of producing frequency accuracies of ±7.5ppm (Parts Per Million) over a temperature range of -40°C - +85°C. The typical oscillation amplitude of this device is 15mV - 30mV.The CE3392-64.000 oscillator is a surface mount device, provided in either a PDIP-8 package or an SOIC-8 package. It consists of a quartz crystal, a bipolar amplifier, a temperature sensitive resistor and an internal voltage regulator. The device is extremely small in size and can be used in applications requiring a small PCB circuit layout.The basic working mechanism of an oscillator, of which the CE3392-64.000 is an example, is the simple mechanical resonant properties of quartz crystals. The quartz crystal is a piezoelectric material which vibrates at a specific frequency when an electric signal is applied to it. The electrical signal causes the atoms of the quartz to vibrate, producing a mechanical resonance. This vibrational energy then converts back into an electrical signal, which is fed back into the circuit in order to sustain the oscillation.The circuitry in the CE3392-64.000 is designed to take advantage of this resonance and to amplify the signal to its oscillation frequency. Within the device, there is a temperature sensitive resistor which compensates for temperature fluctuations in order to maintain the accuracy of the oscillation frequency. The oscillator is also equipped with an internal voltage regulator which ensures a constant voltage supply to the quartz crystal throughout its operational temperature range.The oscillation frequency of the CE3392-64.000 is determined mostly by the size of the quartz crystal. The crystal is cut to a specific thickness such that it oscillates at a desired frequency when a specified voltage is applied to it. This is how the device can achieve its very high frequency accuracies.In summary, the CE3392-64.000 is a high performance, low jitter oscillator with a frequency range of 8kHz to 36MHz. It is a highly precise oscillator capable of producing outstanding frequency accuracies of ±7.5ppm over a temperature range of -40°C - +85°C. The device is suitable for use in Quartz Crystal Oscillators (QCOs), Voltage Controlled Oscillators (VCOs) and Phase-Locked Loop circuits (PLLs), and can also be used for general time base and frequency control applications. The oscillation mechanism of such a device is based on the mechanical properties of quartz crystals, which convert electrical signals into mechanical vibrations that can then be fed back into a circuit in order to sustain oscillation at a specific frequency. The precision of such an oscillator is determined by the size of the quartz crystal, which must be cut to a specific thickness to achieve the desired frequency when a specified voltage is applied.
