Description
AI
[ZL30644A](https://www.microchip.com/en-us/product/zl30644a) is recommended as the replacement for new designs.
The ZL30174 features four independent flexible rate conversion clock channels via four digital PLLs and four clock generators. Each channel accepts and generates any frequency from 1 Hz to 900 MHz to support any communication service over optical networks. The ZL30174 operates from a single crystal resonator or clock oscillator supporting up to ten input references configurable as single ended or differential. It generates up to 12 high performance outputs.
