Introduction

Pin Configurable and Selectable Oscillators are a popular choice for cost effective and reliable frequency control solutions in today\'s digital age. The 516CDA000109AAG is one such example, providing both low power consumption and a variety of frequency options to suit any application. The device, developed by Epson, is a multi-functional CMOS Narrowband oscillator (NCO), capable of taking in a single square wave, and outputting multiple frequencies within the range specified. The 516CDA000109AAG gives the user the highest available frequency accuracy, with ±1~3Hz changes over the full operating temperature range, making it an ideal choice for applications that demand precision and stability.

Application Field& Working Principle

The 516CDA000109AAG is mainly used for communications, instrumentation, metering, and telemetry applications. The device\'s frequency can be programmed easily, simply by setting the frequency on the internal oscillators as a function of the pins. The device has an array of frequency inputs, pin selection depending on the input voltage. Each of the seven frequency pins can be set to one of two voltages, which allows the user to select different frequency ranges. This flexibility makes the 516CDA000109AAG particularly attractive for frequency control applications. The device consists of three main components: an NCO, a frequency programming logic circuit, and the pin selection circuit. The NCO creates a square waveform, which is then fed into the frequency programming logic circuit. This circuit processes the NCO output signals, and depending on the value of the voltage on the frequency pin selection circuit, the output frequency is determined. The output frequency can then be selected by varying the value of the voltage. The noise performance of the device is impressive, boasting low noise figure and stable operation over temperature. In addition, the device has an operating temperature range of -40°C to +85°C, making it suitable for any commercial application. Finally, the device is housed in a miniaturized 3-pin SOP package, allowing it to be used in a variety of applications where board space is limited.

Conclusion

The 516CDA000109AAG oscillator is an ideal choice for precision frequency control applications. Low power consumption and flexibility allow the user to select different frequency ranges, along with an impressive operating temperature range. The device is also housed in a miniaturized 3-pin SOP package, providing an attractive option for customers who are limited in board space. Overall, Pin Configurable and Selectable Oscillators such as the 516CDA000109AAG remain a popular choice for cost-effective frequency control solutions.
