1 FUNCTIONAL DESCRIPTION The XRK49911 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.
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.
The integrated PLL allows external load and transmission line delay effects to be canceled achieving zero delay capability.
Combining the zero delay capability with the selectabl...
