83904I-02

Low Skew,1-to-4,Crystal-to-LVCMOS/LVTTL Fanout Buffer

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.

Features

  • Four LVCMOS / LVTTL outputs, 19Ω output impedance at VDD = VDDO = 3.3V
  • Two crystal oscillator input pairs LVCMOS / LVTTL clock input
  • Crystal input frequency range: 12MHz – 38.88MHz
  • Output frequency: 200MHz (maximum)
  • Output skew: 40ps (maximum) at VDD = VDDO = 3.3V
