Description
Short Form Data Sheet
The ZL30157 Dual Channel Universal Clock Translator, part of ClockCenter platform of Synchronous Clock devices
by Microsemi
®
, 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 two independent digital phase-locked loops (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 range of digital bus
clocks.
