.AD9959数据手册（部分）GENERAL DESCRIPTION概述The AD9959 consists of four direct digital synthesizer (DDS) cores that provide independent frequency, phase, and amplitude control on each channel. This flexibility can be used to correct imbalances between signals due to analog processing, such as filtering, amplification, or PCB layout-related mismatches. Because all channels share a common system clock, they are inherently synchronized. Synchronization of multiple devices is supported. The AD9959 can
