    2022年晶振發展方向:高精度,高穩定性及低相噪

    2022年晶振發展方向:高精度,高穩定性及低相噪

    (1月26日發射升空的陸地探測一號01組A星在軌成功成像,載荷實現多項技術突破。)

    The need for quality, high precision timing devices is increasing daily. The heart of all communications is linked directly to a stable and dependable source of frequency control. Computer networks, data switching and transmission systems, the Global Positioning System (GPS), test instrumentation, and wireless and RF communications systems all rely on precise frequency control at some point in the system.

    我們對高質量、高精度計時設備的需求與日俱增,而所有通信的核心直接連接到穩定可靠的頻率控制源—晶振。計算機網絡、數據交換和傳輸系統、全球定位系統( GPS )、測試儀器、無線和射頻通信系統都依賴于系統中某個點的精確頻率控制。

    In addition, with the requirements for precise frequency control come other concerns such as aging and phase noise. Today’s telecommunications networks must handle millions of data transmissions over great distances within congested systems. Signal degradation due to noise and propagation delay is of major concern to system designers,which is also becoming the goal of manufacturers for hi-quality quartz crystals and oscillators .

    此外,伴隨精確頻率控制的要求,還有其它問題,如晶振電氣參數中的老化率和相位噪聲。今天的5G網絡必須高速處理來自遠距離的海量數據。噪聲和傳播延遲引起的信號退化成為了系統設計者最為關心的問題,這也成為了晶振生產廠家研發及生產的大方向。
