Overview

The 85310I-21 is a low skew, high performance dual 1-to-5 Differential-to-2.5V/3.3VECL/LVPECL Fanout Buffer. The CLKx, nCLKx pairs can accept most standard differential input levels. The 85310I-21 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-21 ideal for those clock distribution applications demanding well defined performance and repeatability.

  • Two differential 2.5V/3.3V LVPECL / ECL bank outputs
  • Two differential clock input pairs
  • CLKx, nCLKx pairs can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
  • Maximum output frequency: 700MHz
  • Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLKx input
  • Output skew: 25ps (typical)
  • Part-to-part skew: 270ps (typical)
  • Propagation delay: 1.7ns (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
  • Lead-Free package fully RoHS complaint
