ZL30157GGG20037 Description

The ZL30157 Dual Channel Universal Clock Translator, part of ClockCenter platform of Synchronous Clock devicesby Microsemi®, delivers industry leading synchronization performance for high-speed complex applications. Thehighly integrated and programmable solution provides translation from any input reference frequency to any outputclock frequency and allows designers to replace multiple components with a single chip, simplifying design, andreducing component count and power.The ZL30157 integrates two independent digital phase-locked loops (PLLs), accepts 4 input references, andgenerates 12 programmable clock outputs. One precision synthesizers generates clocks with jitter performancethat can directly drive 10 G PHY devices. One general purpose synthesizers generates a wide range of digital busclocks.2
