AV9172
Low Skew Output Buffer
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. The AV9172 has six configurable outputs. The AV9172-01 version has one output that runs at the same phase and frequency as the reference clock. A second output runs at the same frequency as the reference, but can either be in phase or 180° out of phase from the input clock.
