Clock retriever based on direct digital synthesis for the adaptive method |
摘要 |
<p>A clock retriever designed for ATM (Asynchronous Transfer Mode) systems which need to maintain timing end to end based on the adaptive method, consisting of applying digital processing techniques and oscillators based on direct digital synthesis (DDS) in design of the retriever, which allows retrieval practically between a direct current signal and a maximum frequency with a considerably improved frequency resolution. <IMAGE></p> |
