單通道、整數(shù)N分頻550 MHz PLL

ADF4116/ADF4117/ADF4118均為頻率合成器，可以用來在無線接收機和發(fā)射機的上變頻和下變頻部分實現(xiàn)本振。上述器件由低噪聲數(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計數(shù)器以及雙模預(yù)分頻器(P/P+1)組成。A（5位）、B（13位）計數(shù)器與雙模預(yù)分頻器(P/P+1)配合，可實現(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，則可以實現(xiàn)完整的鎖相環(huán)(PLL)。\n\n所有片內(nèi)寄存器均通過簡單的三線式接口進行控制。\n\n這些器件采用2 ?
