Especially a large number of mixed - signal integrated circuits are used in the electronic equipments , such as radar , communication , navigation , computer etc . traditional test means are already unable to meet the needs of electronic equipments 特別是在雷達(dá)、通訊、導(dǎo)航、計(jì)算機(jī)等電子設(shè)備中大量的使用了混合信號(hào)的集成電路,采用傳統(tǒng)的測(cè)試手段已無(wú)法滿足電子設(shè)備測(cè)試的要求。
Pll frequency synthesizer is increasingly used in microprocessor systems and communication . with the development of integrated circuits and the emergence of soc ( system on a chip ) technology , it has been a fundamental and very important module in analog and mixed - signal integrated circuits 鎖相環(huán)頻率合成器現(xiàn)在日益廣泛地應(yīng)用于通訊、微處理器系統(tǒng)中,并且隨著集成電路的發(fā)展以及soc技術(shù)的出現(xiàn),其已經(jīng)成為超大規(guī)模集成電路中不可或缺的模塊。
