The 85411 is a low skew, high performance 1-to-2 Differential-to-LVDS Fanout Buffer and a member of the family of High Performance Clock Solutions from IDT. The CLK, nCLK pair can accept most standard differential input levels.The 85411 is characterized to operate from a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 85411 ideal for those clock distribution applications demanding well defined performance and repeatability.

Features

  • Two differential LVDS outputs
  • One differential CLK, nCLK clock input
  • CLK, nCLK pair can accept the following differential input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
  • Maximum output frequency: 650MHz
  • Translates any single ended input signal to LVDS levels with resistor bias on nCLK input
  • Output skew: 20ps (maximum)
  • Part-to-part skew: 250ps (maximum)
  • Additive phase jitter, RMS: 0.05ps (typical)
  • Propagation delay: 2.5 ns (maximum)
  • 3.3V operating supply
  • 0°C to 70°C ambient operating temperature
  • Available in lead free (RoHS 6) package
