描述 Description

The 83908I-02 is a low skew, high performance 1-to-8 Crystal Oscillator/Crystal-to-LVCMOS fanout buffer. The 83908I-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 83908I-02 ideal for those applications demanding well defined performance and repeatability.
