A Design of CPPLL for CMMB Broadcasting System

Article Preview

Abstract:

As an important module in CMMB system, the performance of phase locked loop will directly determines the accuracy, purity and synchronization of system clock. In this paper, a high performance CPPLL circuit is designed to make each system clock of base station to get strict synchronization in frequency and phase. Test results show that the performance of this design meets the CMMB system requirements
