The ZL30632B is a network synchronization chip with up to five independent DPLLs, five extremely low output jitter synthesizers plus extraordinary features to ease customers’ design and increase the flexibility. Having new features, such as fast boot, partial reset, per-input DPLL settings, cascading DPLL and NCO holdover, makes the solution 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 ZL30642B, to form full Timing solution for any rack system.
