General Description

The AV9172 is designed to generate low skew clocks for clock distribution in high-performance PCs and workstations. It uses phase-locked loop technology to align the phase and frequency of the output clocks with an input reference clock. Because the input to output skew is guaranteed to ±500ps, the part acts as a “zero delay” buffer.
