The ICS8633-01 is a high performance 1-to-3
Differential-to-3.3V LVPECL Zero Delay Buffer. The
ICS8633-01 has two selectable clock inputs. The CLKx,
nCLKx pairs can accept most standard differential input
levels. Utilizing one of the outputs as feedback to the PLL,
output frequencies up to 700MHz can be regenerated with
zero delay with respect to the input. Dual reference clock
inputs support redundant clock or multiple reference
applications.
