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

The 85211I-01 is a low skew, high performance 1-to-2 Differential-to-HSTL Fanout Buffer. The CLK, nCLK pair can accept most standard differential input levels.The 85211I- 01 is characterized to operate from a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 85211I-01 ideal for those clock distribution applications demanding well defined performance and repeatability. For optimal performance, terminate all outputs.

Features

  • Two differential HSTL compatible outputs
  • One differential CLK, nCLK input pair
  • CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, HSTL, SSTL, HCSL
  • Maximum output frequency: 700MHz
  • Translates any single-ended input signal to HSTL levels with resistor bias on nCLK input
  • Output skew: 30ps (maximum)
  • Part-to-part skew: 250ps (maximum)
  • Propagation delay: 1ns (maximum)
  • Output crossover Voltage: 0.68V to 0.9V
  • Output duty cycle: 49% - 51% up to 266.6MHz
  • VOH = 1.4V (maximum)
  • 3.3V operating supply
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free RoHS-compliant package
