1. General description
2. Features and benefits
The GTL2008 is a customized translator between dual Xeon processors, Platform Health
Management, South Bridge and Power Supply LVTTL and GTL signals.
Functionally and footprint identical to the GTL2007, the GTL2008 LVTTL and GTL outputs
were changed to put them into a high-impedance state when EN1 and EN2 are LOW, with
the exception of 11BO because its normal state is LOW, so it is forced LOW. EN1 and
EN2 will remain LOW until V
and VREF is at its proper voltage to assure that the outputs will remain high-impedance
through power-up.
The GTL2008 has the enable function 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.
Typically Xeon processors specify a V
0.73 V to 0.76 V. To allow for future voltage level changes that may extend V
V
Characterization results show that there is little DC or AC performance variation between
these V
