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.

A default FSB frequency of 100 MHz is initially set upon power-up when VDD is greater than 1.5 V.

Magnitude comparisons and frequency multiplexing to compute the common FSB frequency occurs when the two 3-bit FSB GTL inputs from the chip sets are valid.
