Thermal Metrology
The maximum Thermal Test Vehicle (TTV) case temperatures (T
CASE-MAX
) can be
derived from the data in the appropriate TTV thermal profile earlier in this chapter.
The TTV T
CASE
is measured at the geometric top center of the TTV integrated heat
spreader (IHS). The following figure illustrates the location where T
CASE
temperature
measurements should be made.

Fan Speed Control Scheme with Digital Thermal Sensor
(DTS) 1.1
To correctly use DTS 1.1, the designer must first select a worst case scenario T
AMBIENT
,
and ensure that the Fan Speed Control (FSC) can provide a Ψ
CA
that is equivalent or
greater than the Ψ
CA
specification.
The DTS 1.1 implementation consists of two points: a Ψ
CA
at T
CONTROL
and a Ψ
CA
at
DTS = -1.
