在CMOS内集成一个32位相位累加器、正弦和余弦查找表以及一个10位DAC的数控振荡器

AD7008直接数字频率合成器芯片是一款数控振荡器，在单个CMOS芯片内集成了一个32位相位累加器、正弦与余弦查找表以及一个10位DAC。提供相位调制、频率调制和同相正交幅度调制功能，适合QAM和SSB的生成。最高支持20 MHz和50 MHz时钟速率。频率控制精度可达40亿分之一。通过并行微处理器接口或串行接口加载寄存器可实现调制。频率选择引脚允许每个周期在两个频率之间做出选择。串行和并行接口可各自独立且与DDS时钟异步工作；传输控制信号在内部完成同步，防止亚稳态现象。同步器可被旁路，以降低微控制器时钟与DDS时钟同步时的传输延迟。关断引脚允许外部控制关断模式（亦可通过微处理器接口访问）。A
