Description

The ZL30633AS 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. The eToD features include a 3-wire MiToDBasic output interface and a 1-wire MiToDSync input/output interface. 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**](https://www.microchip.com/en-us/product/ZL30642A), to form full SyncE&IEEE1588 Timing solution for any rack system.
