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.
