VCXO是一種晶體振蕩器,其輸出頻率根據(jù)施加的控制電壓而變化。VCXO壓控晶體振蕩器輸出頻率的變化以百萬(wàn)分之一(ppm)為單位,如果計(jì)算中包括穩(wěn)定性和老化,則稱為牽拉能力、總牽拉范圍或絕對(duì)牽拉范圍(APR)。VCXO由晶體和振蕩器電路以及變?nèi)荻O管和支持電路組成。石英的高品質(zhì)因數(shù)允許小范圍的頻率牽引。它們還具有低抖動(dòng)和低相位噪聲的高性能。
VCXOs用于微調(diào)工作頻率,通常與鎖相環(huán)(PLL)配合使用。VCXO中的拉取能力可以變化。有些只需要50ppm的拉力,而有些可能需要數(shù)百ppm的拉力。VCXOs的一些應(yīng)用包括電信、測(cè)試和測(cè)量以及廣播設(shè)備。

The Vishay journey began with one man, Dr. Felix Zandman, and a revolutionary technology. From there we would grow and strengthen over decades, arriving where we are today: one of the world’s most trusted manufacturers of electronic components. From discrete semiconductors to passive components; from the smallest diode to the most powerful capacitor, Vishay’s breadth of products is the very foundation that brings modern technology to life, every day, for everyone. We call it The DNA of tech.™
This DNA is more than infrastructure for today’s most vital electronic products, it’s a platform to enable growth. Vishay is well-positioned to propel such timely macroeconomic growth drivers as sustainability, connectivity and mobility. Through R&D, manufacturing, engineering, quality, sales and marketing, we generate the essential components that enable inventors and innovators to create new generations of products—ones that span many sectors: automotive, industrial, consumer, computer, telecommunications, military, aerospace, and medical.
Together with the manufacturers of today and tomorrow’s most compelling electronic innovations, names you know, we are enabling next level automation in factories, the electrification of the automobile, 5G network technology, and the rapid expansion of connectivity across everything (IoT) to highlight a few areas of strong growth. This diversity of opportunity is the reason Vishay has thrived, and why we are driven to be the DNA behind the success of our customers and partners and to be part of making a future that’s safer, sustainable and more productive.
