The 85310I-11 is a low skew, high performance 1-to-10 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer. The CLKx, nCLKx pairs can accept most standard differential input levels. The 85310I-11 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 85310I-11 ideal for those clock distribution applications demanding well defined performance and repeatability.

Features

  • Ten differential 2.5V, 3.3V LVPECL/ECL output pair
  • Two selectable differential input pairs
  • Differential CLKx, nCLKx pairs can accept the following interface levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
  • Maximum output frequency: 700MHz
  • Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLK input
  • Output skew: 30ps (typical)
  • Part-to-part skew: 140ps (typical)
  • Propagation delay: 2ns (typical)
  • Additive phase jitter, RMS: <0.13ps (typical)
  • LVPECL mode operating voltage supply range: VCC = 2.375V to 3.8V, VEE = 0V
  • ECL mode operating voltage supply range: VCC = 0V, VEE = -3.8V to -2.375V
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free RoHS compliant package
