在CMOS內(nèi)集成一個32位相位累加器、正弦和余弦查找表以及一個10位DAC的數(shù)控振蕩器

AD7008直接數(shù)字頻率合成器芯片是一款數(shù)控振蕩器，在單個CMOS芯片內(nèi)集成了一個32位相位累加器、正弦與余弦查找表以及一個10位DAC。提供相位調(diào)制、頻率調(diào)制和同相正交幅度調(diào)制功能，適合QAM和SSB的生成。最高支持20 MHz和50 MHz時鐘速率。頻率控制精度可達(dá)40億分之一。通過并行微處理器接口或串行接口加載寄存器可實(shí)現(xiàn)調(diào)制。頻率選擇引腳允許每個周期在兩個頻率之間做出選擇。串行和并行接口可各自獨(dú)立且與DDS時鐘異步工作；傳輸控制信號在內(nèi)部完成同步，防止亞穩(wěn)態(tài)現(xiàn)象。同步器可被旁路，以降低微控制器時鐘與DDS時鐘同步時的傳輸延遲。關(guān)斷引腳允許外部控制關(guān)斷模式（亦可通過微處理器接口訪問）。A
