5.2Thermal Metrology

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

5.3Fan 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 TAMBIENT, and ensure that the Fan Speed Control (FSC) can provide a ΨCA that is equivalent or greater than the ΨCA specification.

The DTS 1.1 implementation consists of two points: a ΨCA at TCONTROL and a ΨCA at DTS = -1.
