General description

The GTL2007 is a customized translator between dual Xeon processors, Platform Health

Management, South Bridge and Power Supply LVTTL and GTL signals.

The GTL2007 is derived from the GTL2006 with an enable function added that disables

the error output to the monitoring agent for platforms that monitor the individual error

conditions from each processor. This enable function can be used so that false error

conditions are not passed to the monitoring agent when the system is unexpectedly

powered down. This unexpected power-down could be from a power supply overload, a

CPU thermal trip, or some other event of which the monitoring agent is unaware.

A typical implementation would be to connect each enable line to the system power good

signal or the individual enables to the VRD power good for each processor.

The Nocona and Dempsey/Blackford Xeon processors specify a VTT of 1.2 V and 1.1 V,

as well as a nominal Vref of 0.76 V and 0.73 V respectively. To allow for future voltage level

changes that may extend Vref to 0.63 of VTT (minimum of 0.693 V with VTT of 1.1 V) the

GTL2009 allows a minimum Vref of 0.66 V. Characterization results show that there is little

DC or AC performance variation between these levels.

The GTL2007 is the companion chip to the GTL2009 3-bit GTL Front-Side Bus frequency

comparator that is used in dual-processor Xeon applications.
