Introduction

DSC2210FI2-A0028T is a pin configurable or selectable oscillator，which can provide customers with up to 27.5MHz of frequencies. It is built with DSC\'s SOI (silicon-on insulator) technology process and the size of its package is only 1.6x1.4mm.

Application Field

DSC2210FI2-A0028T is suitable for Wireless LAN, Bluetooth and WLAN applications. In Wireless LAN (WLAN) applications, it can be used in Access Points, Bridges, Routers and other networking devices operating in the 5GHz range. In addition, it is also suitable for Bluetooth applications where it can provide a reliable connection between Bluetooth devices, enabling seamless data transmission.

Features

DSC2210FI2-A0028T offers some features that make it an attractive oscillator solution. Firstly, it requires only one external load capacitor and one trim capacitor to operate, reducing the tooling cost of the system. Secondly, its low phase noise performance and wide temperature range of -40℃ to 125℃ make it suitable for a variety of applications. Thirdly, it is easy to install and configure as its pin configuration is flexible and can be set to different frequencies. Finally, it has low power consumption, making it a cost-effective solution.

Working Principle

The DS2210FI2-A0028T uses a unique silicon-on-insulator (SOI) process for chip manufacturing. This is a type of technology where a thin layer of both silicon and insulating material are layered on top of a silicon substrate. This process results in a number of advantages, including improved electrical performance, lower series resistance, better noise performance, and also increased reliability due to reduced stress. The oscillator consists of a voltage-controlled crystal oscillator circuit (VCXO) and a programmable oscillator circuit (P0C). The VCXO circuit is used to control the output frequency and the POC circuit is used to adjust the output frequency. The frequency range of the oscillator is affected by two external components: a thin film resistor (Rss) and a trim capacitor (Css). The resistor is used to tune the output frequency while the trim capacitor is used to adjust the accuracy of the output frequency. Moreover, the trim capacitor (Css) is also used to adjust the frequency foldback point. This is important as it helps to ensure that the oscillator operates within the specified frequency range.

Summary

In summary, the DS2210FI2-A0028T pin configurable/selectable oscillator is suitable for many applications, such as Wireless LAN, Bluetooth, and WLAN. It offers superior noise performance and low power consumption, allowing for cost-effective operation. It also requires only two external components for operation: one trim capacitor and one load capacitor, resulting in reduced tooling costs. The underlying technology used for the oscillator is a unique SOI process, which results in improved electrical performance, lower series resistance, and higher reliability. Finally, the frequency foldback point can be set using the trim capacitor for maximum accuracy.
