用一片LaticeispLSI器件设计了一种包含整数分频和小数分频的快速数字频率合成器,该数字频率合成器是实现多频移频键控的核心技术。详细介绍了其工作原理、设计思路和is-pLSI可编程逻辑器件的应用技术。
A Latticeisp LSI device is designed with a fast digital frequency synthesizer that includes an integer divider and a fractional divider, which is the core technology for multi-frequency shift keying. Described in detail its working principle, design ideas and is-pLSI programmable logic device application technology.
