www.DataSheet4U.com FEBRUARY 2007 XRK4993 3.3V PROGRAMMABLE SKEW CLOCK BUFFER REV. 1.0.0 FUNCTIONAL DESCRIPTION The XRK4993 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 ouputs, arranged in four banks, can each drive 75Ω terminated transmission lines while delivering minimal and specified output skews and full-swing Low Voltage TTL logic levels. Banks A, B, C (two outputs per bank) can be individually selected for one of nine delay or function configurations through two dedicated three-level inputs. These outputs are able to lead or lag the CLKIN input reference clock by up to 6 time units from their nominal "zero" skew position.
