LOW SKEW, 1-TO-4, CRYSTAL-TOLVCMOS/LVTTL FANOUT BUFFER
ICS83904-02
GENERAL DESCRIPTION
The ICS83904-02 is a low skew, high perforIC S mance 1-to-4 Crystal Oscillator/Crystal-to-LVCMOS HiPerClockS™ Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The ICS83904-02 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.
