Microsemi

Overview

The ZL30152 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 ZL30152 accepts 2 single ended or differential input references and generates 6 high performance 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.
