Network Interfaces, beginning on page 51 Real-Time Clock (RTC) The Owl features a real-time clock/calendar (RTC) circuit. The Owl supplies RTC voltage in S5, S3, and S0 states, but requires an external +2.75 V to +3.3 V battery connections. Refer to the section titled Battery Power Options on page 23 for more information.
Molex 051353-0800 Power Requirements The Owl requires a single +8 to +30 VDC supply capable of providing at least 35 W average power that can also provide a peak power of 50 W. The input DC supply creates both the standby and payload voltages provided to the CPU module.
Board Features The specifications for typical operating current do not include any off-board power usage that fed through the Owl power connector. Expansion boards and USB devices plugged into the board will source additional power through the Owl power connector.
Board Features Battery Power Options The battery circuit on the Owl provides power for the Real-Time Clock (RTC) and power to store BIOS Setup utility settings in non-volatile RAM. The Owl has multiple options for providing battery power: Use an external battery (the VL-CBR-0203, for example) connected to the board through the battery connector.
The User I/O connector (shown in Figure 19 on page 36) includes an input for a push-button reset switch. Shorting pin 18 to ground causes the Owl to reboot. This must be a mechanical switch or an open-collector or open-drain active switch with less than a 0.5V low-level input when the current is 1 mA.
Board Features CPU Fan Connector The Owl provides a four-pin CPU fan connector. The next figure shows the location and pin orientation of the CPU fan connector. Figure 10. Location and Pin Orientation of the CPU Fan Connector The table below provides the pinout of the CPU fan connector.

This section provides guidelines for the overall system thermal engineering effort. Heat Plate The heat plate supplied with the Owl is the basis of the thermal solution. The heat plate draws heat away from the CPU chip as well as other critical components. Some components rely on the ambient air temperature at or below the maximum specified 85 ºC temperature.
Lower the system level temperature requirement as needed CPU Thermal Trip Points The CPU cores in the Owl have their own thermal sensors. Coupled with these sensors are specific reactions to three thermal trip points. Table 20 describes the three thermal trip points.
Due to the unknown nature of the entire thermal system, or the performance requirement of the application, VersaLogic cannot recommend a particular thermal solution. This information is intended to provide guidance in the design of an overall thermal system solution.
Thermal Considerations Heat Sink with Fan Considerations: The heat sink and fan combination cools the CPU when it is running in high temperature environments, or when the application software is heavily utilizing the CPU or video circuitry. The fan assists in cooling the heat sink and provides additional air movement within the system.
Configuration: loopback, 2x USB2 loopback, 2x MPEe-E5E, 6x network As shown below, the quad core version of the Owl will typically require a heat sink + fan for operation above 80 ºC, at >90% CPU utilization. Table 26. Test 2 - Quad Core Thermal Test Results...
Heat Plate Down The next figure (a representative image of a similar VersaLogic product) shows the assembly. Use this assembly method if you are attaching the Owl to a larger thermal solution such as a metal chassis/enclosure. Figure 36. An Example of Hardware Assembly with Heat Plate Down A thermal interface compound must be applied to the heat plate to bond it to the mounting plate or other surface to which the Owl is mounted.
Thermal Considerations Heat Plate Up Use this assembly method if you are adding a heatsink to the standard Owl heat plate. Figure 37 (a representative image of a similar VersaLogic product) shows an EPU assembly including the optional heatsink. Figure 37. An Example of Hardware Assembly with Heat Plate Up The recommended assembly method for this configuration is as follows: 1.
Thermal Considerations Installing the VL-HDW-415 Heat Sink Fan Position the fan assembly Using the figure below as a guide, align the mounting holes of the heat sink fan with the four holes in the passive heat sink. Position the fan so that its power cable can easily reach its mate.
Thermal Considerations Installing the VL-HDW-408 Heat Pipe Block Apply the Arctic Silver Thermal Compound (VL-HDW-401) Apply the thermal compound to the heat plate using the method described on the Arctic Silver website - http://www.arcticsilver.com/. The 4 mm heat pipes will also typically have the thermal compound applied to where the pipes contact both the heat plate and the block.
