The ZL30644A is a feature-rich line card solution with up to seven 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 line card timing applications such as routers, switches, optical transparent network and 4G/5G wireless base stations. We also have ZL3063x as SyncE Timing Card Synchronizer, such as ZL30634A, or ZL3073x as SyncE&1588 Timing Card Synchronizer, such as ZL30735A, to form full SyncE&IEEE1588 Timing solution.
