Introduction
Pin Configurable/Selectable Oscillators are a type of oscillators used in the semiconductor industry. They usually have multiple pins that are individually programmable or selectable to generate different clock signals. One example of this type of oscillator is the DSC400-0444Q0009KI2. This article will cover its application field as well as its working principle.Application Field
The DSC400-0444Q0009KI2 is a small size oscillator that is ideal for use in a variety of applications, particularly those that require a low power consumption and a high performing clock source. It is suitable for use in Communications, Test & Measurement, Medical, Industrial, Automotive and many more applications.Due to its ultra-low power consumption of typically 1.2mW and a reliable clock frequency stability of ±100ppm over the temperature range 0~75°C, the DSC400-0444Q0009KI2 oscillator is suitable for use in applications with stringent power requirements.This oscillator also uses a 3-wire serial interface, that allows the internal registers of the chip to be programmed and read in order to customize the device to the customer’s application.Working Principle
The DSC400-0444Q0009KI2 is a miniature quartz oscillator that is able to generate a wide range of frequency outputs. It is based on a Pierce oscillator circuit. The Pierce oscillator circuit is a combination of an amplifier and an LC network.In the Pierce oscillator circuit, a trans-conductance amplifier is used to ensure that the voltage across the tank circuit (the LC network) is zero. The amplifier is connected between the two terminals of the tank circuit. As the amplifier is an active component, it needs a DC power supply to function.The LC network in the oscillator is composed of the quartz crystal and around 10pF capacitors. The quartz crystal has a precisely controlled resonance frequency, allowing it to generate a very stable output frequency. The capacitors form a parallel resonance with the crystal, creating a high Q factor which gives a high frequency stability.The oscillator also contains a special programmable logic chip (PLC). This chip is used to control the oscillator’s output frequency by adjusting the capacitors. The frequency of the oscillator can be programmed by writing to the PLC’s internal registers. This allows the customer to tailor the oscillator to their specific requirements.Conclusion
The DSC400-0444Q0009KI2 is an example of a Pin Configurable/Selectable Oscillator, a type of oscillator used in semiconductor applications. It is suitable for use in a variety of applications due to its low power consumption and reliable clock frequency stability. It is based on the Pierce oscillator circuit, which includes a trans-conductance amplifier and an LC network composed of a quartz crystal and 10pF capacitors. The oscillator also contains a programmable logic chip which allows the customer to tailor the frequency to their specific requirements.The specific data is subject to PDF, and the above content is for reference
