1 GSPS正交數(shù)字上變頻器，內(nèi)置18位IQ數(shù)據(jù)路徑和14位DAC

AD9957可用作通用I/Q調(diào)制器與捷變上變頻器，適合視成本、尺寸、功耗和動(dòng)態(tài)性能為關(guān)鍵因素的通信系統(tǒng)。它在單芯片上集成了一個(gè)高速直接數(shù)字頻率合成器(DDS)、一個(gè)高性能、高速14位數(shù)模轉(zhuǎn)換器(DAC)、時(shí)鐘乘法器電路、數(shù)字濾波器以及其它DSP功能，為有線或無(wú)線通信系統(tǒng)中的數(shù)據(jù)傳輸提供基帶上變頻。\n\n AD9957是正交數(shù)字上變頻器(QDUC)系列中的第三款器件，另外兩款器件是AD9857和AD9856。它的工作速度、功耗和頻譜性能均有所提升。與前兩款產(chǎn)品不同，它支持可用于I/Q基帶數(shù)據(jù)的16位串行輸入模式?；蛘?，也可以對(duì)這款器件進(jìn)行編程，用作單音正弦源或插值DAC。 \n\n ? 1 GSPS內(nèi)部時(shí)鐘速度（高達(dá) 400 MHz模擬輸出）\n\n? 集成1 GSPS、14位DAC\n\n? 輸入數(shù)據(jù)速率：250 MSPS\n\n? 相位噪聲 ≤ ?125 dBc/Hz（1 kHz偏移，400 MHz載波）\n\n? 卓越的動(dòng)態(tài)性能：>80 dB 窄帶 SFDR\n\n? 8個(gè)可編程配置文件，支持移位鍵控\n\n? Sin(x)/(x)校正（反正弦濾波器）\n\n? 參考時(shí)鐘倍頻器\n\n? 內(nèi)部振蕩器，支持單晶體操作;
