The ZL30631 is a feature-rich network synchronization solution with up to four independent DPLLs and five extremely low output jitter synthesizers. This solution is ideal for Synchronous Ethernet (SyncE) central timing 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.
