My group design a SOC. As you know,the SOC need a pll to provide higher clock ,but we can not find a proper pll in .25 process. so we decide use a high oscillate and dpll to resolve the probleme ,but i am a beginner ,i do not know how to implemet it . Will you please tell me about how to implemet it and where can i find some meteraials about implement and dpll.Thanks in advance !!!
could you be more specific about the design? like the frequency, etc. I just did one adpll design, however, the implementation all depends on your applications.
