www.DataSheet4U.com xr OCTOBER 2005 XRK4991 3.3V HIGH-SPEED (85 MHZ) PROGRAMMABLE SKEW CLOCK BUFFER REV. 1.0.1 FUNCTIONAL DESCRIPTION The XRK4991 is a 3.3V High-Speed Low-Voltage Programmable Skew Clock Buffer. It is intended for high-performance computer 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. Each bank (two outputs per bank) can be individually selected for one of nine delay or function configurations through two dedicated tri-level inputs.
