XRK49911 Datasheet

Skew Clock Buffer

Manufacturer: Exar (now MaxLinear)

XRK49911 Overview

The XRK49911 is a 3.3V High-Speed Low-Voltage Programmable Skew Clock Buffer. It is intended for high-performance puter systems and offers user selectable control over system clock functions to optimize timing. Eight outputs, arranged in four banks, can each drive 50Ω terminated transmission lines while delivering minimal and specified output skews and full-swing Low Voltage TTL logic levels.

XRK49911 Key Features

  • 3.75- to 110-MHz output operation
  • All output pair skew <100 ps typical
  • Three skew grades
  • 2 : tSKEW0<250ps -5 : tSKEW0<500ps -7 : tSKEW0<700ps
  • Selectable output functions
  • Cycle-Cycle Jitter
  • Zero input-to-output delay
  • 50% duty-cycle outputs
  • LVTTL outputs drive 50Ω terminated lines
  • Operates from a single 3.3V supply
