Description

The ZL30735 is a feature-rich network synchronization solution with up to eight independent DPLLs and five extremely low output jitter synthesizers combined with IEEE 1588-2008 Precision Time Protocol Stack and Synchronization Algorithm software packages. This is an ideal central Timing solution 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**](https://www.microchip.com/wwwproducts/en/ZL30642A), to form full SyncE&IEEE1588 Timing solution for any rack system.
