... Rev. 01 — 22 September 2005 1. General description The GTL2009 is designed for the Nocona and Dempsey/Blackford dual Intel Xeon processor platforms to compare the Front-Side Bus (FSB) frequency settings and set the common FSB frequency at the lowest setting if both processor slots are occupied or the FSB setting of the occupied processor slot if only one processor is being used ...

... regulation GTL2009. No firm answer for this can be given since the time it takes for V regulation varies from 100 ms to 1000 ms, and the rise time of V GTL2009 outputs are valid after the GTL inputs are valid plus 19.6 ns (worst-case propagation delay of the GTL-to-LVTTL path). ...

... Fig 3. Application diagram 8.1 Frequently asked questions Question 1: When the GTL2009 is unpowered, the LVTTL inputs may be pulled up to 3.3 V and we want to make sure that there is no leakage path to the power rail under this condition. Are the LVTTL inputs high-impedance when the device is unpowered and will ...
