Skew Clock Buffer

Manufacturer: Exar (now MaxLinear)

XRK4991A Overview

The XRK4991A 3.3V High-Speed Low-Voltage Programmable Skew Clock Buffer offers user selectable control over system clock functions to optimize the timing of high-performance puter systems. Eight individual drivers, arranged as four pairs of user-controllable outputs, can each drive terminated transmission lines with impedances as low as 50Ω while delivering minimal and specified output skews and full-swing logic...

XRK4991A Key Features

  • Ref input is 5V tolerant
  • 3 pairs of programmable skew outputs
  • Low skew: 200ps same pair, 250ps all outputs
  • Selectable positive or negative edge
