VTTPWRGD Transition Parameter Recommendation
Parameter
Recommendation
Transition time (300 mV to 900 mV)
Less than or equal to 100 s
In addition, the VTT_PWRGD signal should have reasonable transition time through the transition
region. A sharp edge on the signal transition will minimize the chance of noise causing a glitch on this
signal. Intel recommends the following transition time for the VTT_PWRGD signal.
4.3.1.2.1
Transition Region
The transition region covered by this requirement is 300 mV to 900 mV. Once the VTTPWRGD signal
is in that voltage range, the processor is more sensitive to noise, which may be present on the signal.
The transition region when the signal first crosses the 300 mV voltage level and continues until the last
time it is below 900 mV.
4.3.1.2.2
Transition Time
The transition time is defined as the time the signal takes to move through the transition region. A 100-
sec transition time will ensure that the processor receives a good transition edge.
4.3.1.2.3
Noise
The signal quality of the VTTPWRGD signal is critical to the correct operation of the processor. Every
effort should be made to ensure this signal is monotonic in the transition region. If noise or glitches are
present on this signal, it must be kept to less than 100 mV of a voltage drop from the highest voltage
level received to that point. This glitch must remain less than 100 mV until the excursion ends by the
voltage returning to the highest voltage previously received. Please see Figure 22 for an example graph
of this situation and requirements.
