摘要
介绍了可编程控制频率合成器接口类型 ,设计了一种基于 PC并口的频率合成器编程控制装置。接口控制形式有并行和串行两种 ,着重介绍串行接口控制 ,并给出设计实例。
This paper introduced the interface modes of programmable synthesizer, and designed a control unit based on PC print port. There were two kinds of interfaces:parallel and serial interface mode, serial interface was mainly discussed and an example was given for designing.
