Description
AI
The ZL30644 is a feature-rich line card solution with up to seven independent DPLLs and five extremely low output jitter synthesizers. 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**](https://www.microchip.com/wwwproducts/en/ZL30634A), or ZL3073x as SyncE&1588 Timing Card Synchronizer, such as [**ZL30735A**](https://www.microchip.com/en-us/product/ZL30735A), to form full SyncE&IEEE1588 Timing solution.
