一、产品概述
DS852是一种高速直接数字合成器(DDS)。在1.1 GHz(2.2 - GHz时钟频率)可以产生正弦波的尼奎斯特频带。一个5 v电源是必需的。
DS852is a high-speed Direct Digital Synthesizer (DDS) with a frequency tuning resolution of 32 bits and an amplitude resolution of 11 bits. Sine waves in the 1stNyquist band can be generated up to near 1.1 GHz (at a 2.2-GHz clock rate). The initial phase can be reset to zero degrees to start with. The chip has a pair of complementary outputs with 50 back terminations. The frequency of output waveforms can be controlled by thirty-two frequency control bits,Vi[0:31].
DS852accepts either complementary clock inputs or a single-ended clock input and features 50 on-chip back terminations with user-defined threshold. The input signals of frequency word accept LVTTL or CMOS input levels. Only a single –5.0V power supply is required.
