LM15851器件為寬帶采樣和數(shù)字調(diào)諧器件。德州儀器(TI)的千兆次采樣模數(shù)轉(zhuǎn)換器(ADC)技術(shù)支持采用射頻直接對(duì)大范圍頻譜采樣。集成DDC(數(shù)字下變頻器)可進(jìn)行數(shù)字濾波和下變頻轉(zhuǎn)換。所選頻率塊適用于JESD204B串行接口。數(shù)據(jù)以基帶15位復(fù)數(shù)信息形式輸出,以減輕下游處理壓力。根據(jù)數(shù)字下變頻器(DDC)抽取率和鏈接輸出率設(shè)置,該數(shù)據(jù)將通過串行接口的1至5通道輸出。
LM15851器件采用68引腳超薄四方扁平無引線( VQFN)封裝。該器件的工業(yè)環(huán)境運(yùn)行溫度范圍為-40°C≤T A ≤85°C。
