Description
AI
The ZL80132B is a feature-rich network synchronization solution with two independent DPLL clock channels plus three additional DPLLs for NCO Hybrid, Split XO and redundant oscillator modes, and five extremely low output jitter synthesizers. Having new features, such as ePPS, fast boot, partial reset, per-input DPLL settings, cascading DPLL and NCO holdover, makes the solution ideal for server-based 5G DU/CU applications,capable of GPS/GNSS synchronization.The part can be used on mother board, M.2 daughter card, OCP daughter card or PCIe daughter card.
We also have ePPS Timebuffer [ZL80640B](https://www.microchip.com/en-us/product/ZL80640B) and ePPS buffer [ZL40268](https://www.microchip.com/en-us/product/ZL40268) to form full Timing solution for OCP and traditional 5G networks.
