The ZL30640A is a feature-rich TimeBuffer with two independent DPLLs, up to 10 inputs and 20 outputs and embedded Time-of-Day (eToD) features. The eToD features include a 3-wire MiToDBasic output interface and a 1-wire MiToDSync input/output interface. This time-signal fanout solution is ideal to companion timing card or line card timing ICs for 5G telecom systems. Other devices in this family include ZL30731, ZL30732, ZL30732A, ZL30733, ZL30733A, ZL30733AS, ZL30734, ZL30735, ZL30735A, ZL30631, ZL30632, ZL30633, ZL30633AS, ZL30634, ZL30634A, ZL30635, ZL30641, ZL30642, ZL30642A, ZL30642AS, ZL30643, ZL30644, ZL30644A, ZL30645 and ZL30640, which are targeted for 5G SyncE & IEEE1588/PTP timing and line card applications.
