Onboard temperature and voltage monitoring and control is handled by an Analog
Devices ADT7476A chip. This chip is controlled via IIC and can provide the following
functions:

Connector J31 is a keyed three-pin fan header similar to those found in computers. It is
designed to support a 5V DC fan. To bypass the fan controller chip and operate the fan at
full speed, the user can populate connector J32.
For high-power operating conditions, a heatsink and/or fan for the FPGA can be
accommodated on the board. The board does not ship with a heatsink/fan unit but can
accommodate one (for example, Calgreg Electronics Smart-CLIP family of heatsink/fan
assemblies).
A piezo audio transducer
to be played. The piezo is driven by a transistor controlled by the FPGA.
Table 1-19: Piezo Connection
The DB15HD connector (P8) on the board supports connectivity to an external VGA
source. The VGA input codec circuitry utilizes an Analog Devices AD9980 device (U19).
The AD9980 is an 8-bit 95 MSPS interface optimized for capturing YPbPr video and RGB
graphics signals. Its 95 MSPS encode rate supports HDTV video modes and graphics
resolutions up to XGA (1024 × 768 at 85 Hz). The Analog Devices AD9980 device is
controlled by way of the Video IIC bus.
