This commercial integrated chip can be used in the localoscillation circuit, high-accuracy clock generator and so on.
这种商用集成芯片可用于本振合成回路，高精度时钟发生器等。

In receiving mode, through controlling DDS, it produces the localoscillation signal needed by down frequency conversion of the receiving signal. Then the DBF is used to form the receiving beam.
在接收模式下，则利用DDS技术产生接收信号下变频所必需的本振信号，然后采用DBF技术形成接收波束。
