Single frequency source is usually used as local oscillator in communication system and radar system , also as a reference clock in digital circuits , so it is a extensive - applied technique 固定频率源可以在在通讯系统和雷达系统中作为本机振荡器,也可以作为数字电路的基准时钟信号,因此得到了广泛的应用。
In the multi - module mode both trig signal and reference clock are used for synchronization . the functional module supports dma with the dsp , which frees the dsp ' s core processor and entitles the real - time digital signal processing 在数据传输方面无论是通过外部总线接口还是数据链路接口,功能模块与dsp之间都支持dma方式,解放了母板处理器的核心运算单元,使实时信号处理成为可能。
In its digital processing circuit , clock chip with high precision and temperature compensation is uesd as reference clock . high frequency reversible counter is used to count trimmed impulse signal forward or backward and two pathes saw signals are selected timely by multichannel selector 数字信号处理电路采用高精度、具有温度补偿的时钟芯片作为基准时钟,采用高频可逆计数器对整形后的脉冲信号进行正向或逆向计数,采用高性能的多路选择器控制两路saw信号的定时选择。
