Low Skew, 1-to-4, Crystal-to-LVCMOS/ LVTTL Fanout Buffer
83904-02
Data Sheet
GENERAL DESCRIPTION
The 83904-02 is a low skew, high performance 1-to-4 Crystal-toLVCMOS 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.
