ESCRIPTION
The ICS83908I-02 is a low skew, high performance
1-to-8 Crystal Oscillator/3.3V LVCMOS-to-3.3V
LVCMOS fanout buffer and a member of the
HiPerClockS family of High Performance Clock
Solutions from IDT. The ICS83908I-02 has selectable
single ended clock or two crystal-oscillator inputs. There is an
output enable to disable the outputs by placing them into a high-
impedance state.
