PLL頻率合成器

ADF4107頻率合成器在無(wú)線接收機(jī)和發(fā)射機(jī)的上變頻和下變頻部分中，可用來(lái)實(shí)現(xiàn)本振。它由低噪聲數(shù)字鑒頻鑒相器(PFD)、精密電荷泵、可編程參考分頻器、可編程A和B計(jì)數(shù)器以及雙模預(yù)分頻器(P/P+1)組成。A（6位）、B（13位）計(jì)數(shù)器與雙模預(yù)分頻器(P/P+1)配合，可實(shí)現(xiàn)N分頻器(N = BP + A)。此外，14位參考分頻器（R分頻器）允許PFD輸入端的REFIN頻率為可選值。如果頻率合成器與外部環(huán)路濾波器和電壓控制振蕩器(VCO)一起使用，則可以實(shí)現(xiàn)完整的鎖相環(huán)(PLL)。其帶寬極高，因此許多高頻系統(tǒng)可以省去倍頻器，從而簡(jiǎn)化系統(tǒng)架構(gòu)并降低成本。 ? 帶寬：7.0 GHz\n\n? 2.7 V至3.3 V電源供電\n\n? 獨(dú)立的電荷泵電源(VP)可在3 V系統(tǒng)中提供擴(kuò)展的調(diào)諧電壓\n\n? 可編程雙模預(yù)分頻器：8/9、16/17、32/33、64/65;
