Overview

The 83904I-02 is a low-skew, high-performance 1-to-4 crystal-to-LVCMOS fanout buffer. The 83904I-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 83904I-02 ideal for those applications demanding well-defined performance and repeatability.
