6 Product Overview
1.4.5 Power
Table 1-5 provides the power requirements for this module under certain load configurations.
Operating configurations:
 In-rush operating configuration - Windows 8.1
 Idle operating configuration - Windows 8.1
 BIT (Burn-In Test) operating configuration - Windows 8.1; Intel TAT tool
1.4.6 Cooling
The Q7-BT is designed to operate at its maximum CPU speeds of
1.46GHz
and 1.91GHz and
requires a thermal solution to cool the SoC. ADLINK offers a heat spreader as one part of the
cooling solution. Refer to Figure 1-5 for diagram of heat spreader dimensions.

The Q7-BT supports two separate heat spread-
ers—one for board revision A2 and one for board
revision A3. The two versions of the heat spreader
require different order numbers, respectively.
The heat spreader plate requires another form of
cooling, such as a heatsink with a fan. A heat
spreader plate is not a complete thermal solution
for the Q7-BT.
The overall system design must keep the ICs
within their operating temperature specifications.
