ZL30157

In Production

The ZL30157 Dual 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 and allows designers to replace multiple components with a single chip, simplifying design and reducing component count and power. The ZL30157 integrates 2 independent digital PLLs, accepts 4 input references and generates 12 programmable clock outputs.  One precision synthesizers generates clocks with jitter performance that can directly drive 10 G PHY devices. One general purpose synthesizers generates a wide raneg of digital bu...
