The 83904-02 is a low skew, high performance 1-to-4 Crystal-to-LVCMOS Fanout Buffer. The 83904-02 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. Guaranteed output and part-to-part skew characteristics make the 83904-02 ideal for those applications demanding well defined performance and repeatability.\n
