The ZL30733A is a feature-rich network synchronization solution with up to six independent DPLLs, five extremely low output jitter synthesizers and embedded time-of-day (eToD) features combined with IEEE 1588-2008 Precision Time Protocol Stack and Synchronization Algorithm software modules. The eToD features include a 3-wire MiToDBasic output interface and a 1-wire MiToDSync input/output interface. This solution is ideal for applications such as routers, switches, optical transparent network and 4G/5G wireless base stations (CU/DU/RU).

We also have ZL3064x as line card jitter attenuators, such as ZL30642A, to form full SyncE&IEEE1588 Timing solution for any rack system.
