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

NOTICE - The following device(s) are recommended alternatives:

The 854105I is a low skew, high performance 1-to-4 LVCMOS/LVTTL-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage Differential Signaling (LVDS), the 854105I provides a low power, low noise solution for distributing clock signals over controlled impedances of 100?. The 854105I accepts an LVCMOS/LVTTL input level and translates it to LVDS output levels. Guaranteed output and part-to-part skew characteristics make the 854105I ideal for those applications demanding well defined performance and repeatability.

Features

  • Four differential LVDS output pairs
  • One single-ended LVCMOS/LVTTL input
  • CLK can accept the following input levels: LVCMOS, LVTTL
  • Maximum output frequency: 250MHz
  • Translates single-ended input signals to LVDS levels
  • Additive phase jitter, RMS: 0.16ps (typical)
  • Output skew: 72ps (maximum)
  • Part-to-part skew: 350ps (maximum)
  • Propagation delay: 1.75ns (maximum)
  • 3.3V operating supply
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
