Description
AI
The ZL30160 Four Channel Universal Clock Translator, part of Microsemi's ClockCenter platform of Synchronous Clock devices, delivers industry leading synchronization performance for high-speed, complex applications. The highly integrated and programmable solution provides translation from any input reference frequency to any output clock frequency with jitter performance that can directly drive 10 G PHY devices.
The ZL30160 integrates 4 independent digital PLLs, accepts 4 input references and generates 20 programmable clock outputs. The highly integrated solution allows designers to replace multiple components with a single chip, simplifying design and reducing component count and power.
