Clock Generator Selector Guide
Universal clock generators simplify traditional board designs by synthesizing frequencies from either a reference input clock or a common low-cost crystal, providing
low-jitter output clocks. When used together with Microsemi clock distribution fanout buffers, the clock generators provide customers with improved board performance
and complete timing solutions.
