1GSPS，14 bit，3.3 V CMOS直接數(shù)字頻率合成器

AD9910是一款內(nèi)置14 bit DAC的直接數(shù)字頻率合成器（DDS），支持高達(dá)1 GSPS的采樣速率。AD9910采用高級(jí)DDS專利技術(shù)，在不犧牲性能的前提下可極大降低功耗。DDS/DAC組合構(gòu)成數(shù)字可編程的高頻模擬輸出頻率合成器，能夠在高達(dá)400 MHz的頻率下生成頻率捷變正弦波形。\n\n 用戶可以訪問三個(gè)用于控制DDS的信號(hào)控制參數(shù)，包括：頻率、相位與幅度。AD9910利用32 bit累加器提供快速跳頻和頻率調(diào)諧分辨率。在1 GSPS采樣速率下，調(diào)諧分辨率為~0.23 Hz。這款DDS還實(shí)現(xiàn)了快速相位與幅度切換功能。\n\n 用戶可通過串行I/O端口對(duì)AD9910 ? 1 GSPS內(nèi)部時(shí)鐘速率（高達(dá)400 MHz模擬輸出）\n\n? 內(nèi)置1 GSPS，14 bit DAC\n\n? 頻率分辨率：0.23 Hz或以上80 dB 窄帶SFDR\n\n? 串行輸入/輸出（I/O）控制\n\n? Sin（X）/（X）校正（反正弦濾波器）\n\n? 欲了解更多信息，請(qǐng)參考數(shù)據(jù)手冊(cè);
