Oscillators, such as ASGTX-D-212.500MHZ-1-T2, are widely used in various kinds of electronic applications due to their ability to generate sinusoidal waveforms of a fixed frequency. They are employed in numerous applications ranging from radio communication systems and frequency synthizers to digital logic circuits. Among its various forms, some of the most commonly used oscillators are the Pierce circuit, the Hartley circuit, and the Clapp circuit.

The Pierce circuit was introduced by a scientist named Gordon H. Pierce in the early 1950s. It operates on the principle of using a parallel gen-set, formed by two back-to-back diodes, and a series LC (inductor-capacitor) tank which is tuned to the desired frequency. When the gen-set is confronted with a DC voltage, the inductor and capacitor form a tank circuit with an inductive reactance that effectively cancels the capacitive reactance at the frequency for which it is tuned. Thus, a sinusoidal voltage is developed across the gen-set. The Pierce circuit is commonly used in radio transmitter and electronic oscillators.

The Hartley circuit was developed by Ralph V.L. Hartley in 1915. It functions similarly to the Pierce circuit, but has two series LC tanks instead of one. Like the Pierce circuit, it also has two diodes in a parallel arrangement. However, the two tanks are connected to the diode pair via two independent windings. As a result, frequency can be changed by adjusting either of the two tuned circuits. The Hartley circuit is usually applied in communication systems and FM receivers.

And the last of the three commonly used oscillators, the Clapp circuit, was invented by Reginald T. Clapp in 1949. This type of oscillator utilizes two parallel LC tanks, with one of them being tuned to the desired frequency. The two tanks are connected to the center feedback line by two independent windings, and the feedback voltage gain is defined by the turns ratio between the two. Just like the Hartley circuit, it can be used to generate high-stability operation and precise frequency control. As a result, the Clapp circuit is usually applied in various high-precision systems.

ASGTX-D-212.500MHZ-1-T2 is one of the many oscillators using the Pierce circuit as its design base. It is manufactured by Micronetics Inc., a company specializing in miniaturized frequency synthesizers and oscillators. This oscillator operates at a lower-than-normal supply voltage of 3V, and is capable of producing a sine wave at the desired frequency over a wide range of temperature ranges. Its working principle is exactly the same as a standard Pierce circuit; when powered, the gen-set forms a parallel tank circuit with an effective inductive reactance that cancels out the capacitive reactance, producing the required output voltage.

ASGTX-D-212.500MHZ-1-T2 is a wide-range oscillator, designed for use in many types of electronic devices. It has numerous application fields where precision timing is essential, such as radio communication systems, digital logic circuits, frequency synthizers, frequency counters, TV receiver circuits, and many more. Its precise low-voltage operation and its wide operating temperature range make it ideal for various use environments.

Therefore, ASGTX-D-212.500MHZ-1-T2 is an oscillator of choice for a variety of applications. It utilizes normal Pierce circuit principle, and its broad temperature range, operating voltage, and frequency precision make it a perfect fit for various applications where precision timing is crucial.
