Oscillators

Oscillators are used throughout the electronics industry as a means of creating a steady and predictable frequency of electrical waveforms. They can be used for a variety of purposes like generating signals for data communication, sampling, clock-generation, and power regulation. One of the most commonly used oscillators is the ASEMPC-12.352MHZ-LR-T, which is employed in applications like microcontrollers, memory microchips, communication links, and instrumentation.

The ASEMPC-12.352MHZ-LR-T is a PLL (Phase-Locked Loop) oscillator built with a differential pair circuit which produces digital signals with very small, low-power consumption. It provides an output signal in the range of 11.28MHz to 12.56MHz with a frequency stability of ± 50ppm over the operating temperature range between -20°C to 85°C. It features a fast lock-in time of 30µs, high phase noise, and low jitter immune to power supply variations.

The working principle of the ASEMPC-12.352MHZ-LR-T varies from traditional crystal oscillators. It comprises of a dual control voltage, dual-phase detector, programmable charge-pump, and voltage controlled oscillator (VCO) in which the PLL circuit utilizes the programmable charge-pump, dual control voltage, and phase detector to lock the internal oscillator’s output within a certain frequency range. This principle enables the device to generate a clean sine wave output, also known as clock signals.

The dual control voltage present in the circuit helps the programmable PLL to accurately adjust the frequency of the oscillator over wide temperature ranges. The dual-phase detector in the PLL helps to detect if the output frequency is drifting from the predetermined frequency range and adjusts it accordingly. The VCO is responsible for producing the desired output frequency based on the frequency adjustments set by the programmable PLL.

The ASEMPC-12.352MHZ-LR-T oscillator has numerous applications in the field of microprocessors, signal, RF transmission, and many other high-speed communication protocols. It can be used to produce a precise clock rate for microprocessors in order to achieve faster processing times for data applications. It is also used to receive and transmit data in high-speed communication systems like Bluetooth, Wi-Fi, and GSM. It is also used in the instrumentation field to provide accurate frequency measurements.

In conclusion, the ASEMPC-12.352MHZ-LR-T oscillator provides an accurately-tuned clock signal with excellent frequency stability, low phase noise, and fast lock-in time. It is a perfect choice for applications that require reliable frequency sources. This oscillator presents a reliable, low-power solution for high-speed communication and measurement systems, microcontroller-based systems, and a variety of other applications.
