Programmable oscillators encompass a range of frequency, pulse width and phase locked loop (PLL) devices that can be used to generate both analog and digital signals. The SIT8008B-28E is a type of programmable oscillator which has been designed specifically for applications requiring ultra low power consumption, high precision and long battery life. In this article, we will discuss the application field and working principle of the SIT8008B-28E. The SIT8008B-28E is suitable for a wide range of applications due to its ability to supply an ultra-low-power device with ±5ppm accuracy. It is suitable for applications involving GPS receivers, satellite navigation systems, industrial automation systems, and remote sensing devices. Additionally, it can be used to generate time-of-day (TOD) synchronization signals for applications such as modems, point of sale terminals, and biometric systems. The SIT8008B-28E’s power consumption is one of its main advantages, as it uses a mere 93uA of current at 3V in normal operation, and a mere 0.5uA of current at 1.8V in sleep mode. In this way, it is able to provide an ultra-low power solution while still delivering +/- 5ppm (parts-per-million) accuracy over temperatures of -40°C to 85°C. This makes the SIT8008B-28E a reliable choice for applications where stable frequency accuracy is paramount. In order to achieve its high accuracy, the SIT8008B-28E utilizes a PLL circuit consisting of an input oscillator and a Phase Frequency Detector (PFD).The PFD are able to produce a pulse-width modulated (PWM) output signal that is used to adjust the input frequency of the oscillator, allowing for precise frequency control. Moreover, the adjustable reference voltage output of the device enables it to achieve frequency adjustment accuracies of up to 256 times the set frequency value. The SIT8008B-28E also features internal memory that can be used to store up to 128 different configurations, enabling multi-channel applications. Additionally, the device has a “smart power down” feature that can be used to improve power conservation when the device is idle. In conclusion, the SIT8008B-28E is an ideal choice for ultra low-power applications requiring very high accuracy. Its low current consumption, adjustable reference voltage, versatile programming options and smart power-down feature make it suitable for a wide range of applications, ranging from satellite navigation systems to biometric systems to industrial automation systems. The device is capable of providing the most reliable and cost-effective solution for these types of applications.
