510SAB-ABAG programmable oscillators are designed for high precision oven-controlled frequency control in pulsed and analog systems. They possess exceptional noise reduction and thermal stability characteristics, allowing for accurate and reliable performance in a wide range of applications. This article explains the main characteristics of the 510SAB-ABAG and the main applications it is suited for.

Main Features of the 510SAB-ABAG

The 510SAB-ABAG is designed for temperature-compensated and oven-controlled crystal oscillators (TCXO) with very low power consumption. This model offers a wide frequency range and excellent noise reduction. It is available in standard sizes which can be specified as a hermetic, header, or SMT unit. The unit is available with a choice of internal capacitors or a fixed capacitance external resistor. Typical noise reduction features of this model include; a high Q-factor, high short-term stability, low phase noise, and a low temperature drift of ± 1.0 ppm/°C.

The unit is fully programmable with both Analogue and Pulse mode operation. It is capable of being operated from either an AC or DC supply, with an adjustable output voltage accuracy and an adjustable rise time. In analogue mode the output voltage is linear with respect to the frequency, allowing for an accurate tuning of the oscillator to the desired frequency. Pulse mode enables the unit to produce an output frequency accurately, simply and quickly, with the output then being scaled for the desired level.

• Test and measurement
• Timing control (e.g. watches)

The 510SAB-ABAG is also ideal for use in medical applications, such as ECG and EEG instrumentation, where accuracy and stability are critical. Its low power requirements and excellent noise reduction capability makes it well-suited for many battery-operated devices, such as navigation systems and sensing devices for industrial automation.

Working Principle of the 510SAB-ABAG

The 510SAB-ABAG is designed to provide a novel, programmable oscillator for temperature compensated and oven-controlled crystal oscillators. It utilizes a microprocessor-controlled voltage-controlled oscillator (VCO) to provide the frequency control. A quartz crystal and temperature compensation circuitry are incorporated into the unit, allowing it to attain exacting frequency accuracy, phase noise, and stability performance over temperature. The user can set the desired frequency through the unit\'s digital interface, and the output can be programmed to provide an integer frequency or an arbitrary frequency within the frequency range of the device.

The device is powered by an internal battery-backed power supply and provides a long operating life. The unit is also equipped with an external voltage regulator and an MOSFET driver to ensure stable operation. The operating temperature range is -20°C to +90°C. The device also has a self-calibration feature, allowing for automatic offset and gain correction for performance optimization.

Conclusion

The 510SAB-ABAG is an ideal programmable oscillator for precision frequency control applications. It offers superior performance characteristics, allowing for reliable and accurate performance in a variety of applications. The unit is simple to program, and the user can easily select the desired frequency output. Overall, the 510SAB-ABAG is an ideal choice for demanding temperature-compensated and oven-controlled crystal oscillator applications.
