Application of High Speed Programmal Frequency Synthesizer ICS8430
Xin Xu · Microprocessors · 2010
Present a method of building clock sources using ICSI company's ICS8430 frequency synthesizer,for the purpose of enhancing the clock accuracy and stability of digital system.Compare sereral ways of clock generating at first.Then describe the architecture and functions of ICS8430 in particular,and present controlling programs in parallel and serial mode of the chip with VHDL.The serial program is designed with the method of stored wave shifting,which can be used as a general method in other designs.At last,present a typical layout.All the designs have been applied in practice and performed well.
