Introduction

Pin Configurable/Selectable Oscillators provide designers with the flexibility to select and configure the best oscillator for a particular application. Pin Configurable Oscillators such as the ASEMCC3-LR-T3, provide a wide range of oscillating frequencies and offer the highest levels of performance by allowing the user to select a range of adjustable and programmable aspects, such as: Frequency Range, Output Power, Output Voltage, Supply Voltage, Temperature Range and Temperature Coefficient.

Application Field

The ASEMCC3-LR-T3 offers numerous features and is designed to be used in a wide range of applications, including: automotive, medical, telecommunications, industrial, consumer, computing and military. The oscillator is particularly suitable for the demands of applications that require an extremely low jitter signal source and the highest levels of reliability.

Working Principle

The ASEMCC3-LR-T3 uses a specially designed multi-pin device, which features an integrated voltage regulator, that provides on-chip adjustment of the amplitude, frequency and phase shifts of output signal, by controlling the enable and reset pins.The device also uses an integrated, low noise, crystal oscillator, which provides a fundamental frequency of 1.83 MHz. This crystal oscillator is connected to the enable and reset pins and is used to control the output signal parameters.The enable pin is used to control the output signal amplitude and frequency. The enable pin voltage is internally regulated, allowing the user to override the factory settings and to optimize the performance of the device for their needs.The reset pin is used to control the output signal phase shift. The user can vary the reset voltage, and as a result, can achieve a wide range of phase delay values.In addition, the device is also able to accommodate several external components, including capacitors and inductors, which further improves the performance of the oscillator.

Conclusion

The ASEMCC3-LR-T3 is one of the most versatile pin configurable/selectable oscillators available on the market today. Thanks to its integrated voltage regulator, the user can easily adjust the amplitude, frequency and phase shift of the output signal without having to deal with complex circuitry. This flexibility is ideal for designs that require a reliable and low jitter signal source for a variety of applications.
