83904-02 - Crystal-to-LVCMOS / LVTTL Fanout Buffer

Datasheet Summary

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.

Features

  • Four LVCMOS/LVTTL outputs, 19Ω typical output impedance @ V = V = 3.3V DD DDO.
  • Two Crystal oscillator input pairs One LVCMOS/LVTTL clock input.
  • Crystal input frequencry range: 12MHz.
  • 38.88MHz.
  • Output frequency: 200MHz (maximum).
  • Output Skew: 40ps (maximum) @ V = V = 3.3V DD DDO.
  • RMS phase jitter @ 25MHz output, using a 25MHz crystal (100Hz.
  • 1MHz): 0.16ps (typical) @ V = V = 3.3V DD.

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.
