The ZL80732 is a feature-rich network synchronization solution with two independent DPLL clock channels plus three additional DPLLs for NCO Hybrid, Split XO and redundant oscillator modes, and five extremely low output jitter synthesizers. This solution is combined with IEEE 1588-2008 Precision Time Protocol Stack and Synchronization Algorithm software modules and ideal for applications such as 5G Distributed Units (DU), Centralized Units (CU) and Radio Units (CU).

Another device in this family is the ZL80032 for 5G synchronous ethernet (SyncE) central timing applications.
