Pin Configurable/Selectable Oscillators have become popular in many applications, from automotive to communications. And 534DA000771DG is one of them. This product is an economical and reliable CMOS pin configurable oscillator, which is easy to use and supports a frequency range from 0.9MHz to 230MHz. It is available in different packages and frequency stability options including 3.2*10-5, 2.5*10-5, 2.0*10-5 and 1.5*10-5. In addition, there are also temperature options available, including 40°C to 85°C, 40°C to 105°C, and -40°C to 85°C, etc.
Besides the obvious advantage of being pin-configured, 534DA000771DG oscillators also offer more convenience. Compared to conventional oscillators of the same structure, they do not require any external components, and feature higher coarse and finer frequency setting accuracy, wide range frequency selection and fast frequency settling time. Its frequency adjustment range is variable and can be configured by different pin combinations. Besides, accurate frequency temperature characteristics and low duty cycle distortion are also provided.

In terms of its application field, 534DA000771DG oscillators can be widely used in high-frequency signal generators, digital sampling circuits, TV tuners, digital signal processors and other test equipment. In the process of working, it kindly accomplish accurate frequency output by precisely setting the specific frequency.For the actual working principle of 534DA000771DG oscillators, the core part of their internal circuit is a linear resonator. The frequency would be adjusted by the active devices and some external circuits, such as Schmitt trigger, HF loop and NAND gate etc. The Schmitt trigger would connect the two resistors to divide voltage, and the HF loop and NAND gate would be used to adjust the voltage. And then it disconnects the resonance circuit and connects a resistor, capacitor and a buffer output, in order to link the buffer amplifier to form the closed-loop frequency adjustment.In conclusion, as its application field and working principle have been outlined, 534DA000771DG oscillators are truly an economical and reliable pin-configurable oscillator which can be widely used in many fields.
