Development Board Components
VGA Video Port
The Cyclone II FPGA Starter board includes a video connector (Figure 2–28) that connects to an on-board 4-bit video DAC. The connector is a standard DB15 15-pin analog VGA connector. Refer to
“VGA DAC” on page 2–2 for a description of the circuitry attached to this connector.
Figure 2–28. VGA Connector
Audio Ports
The audio circuit provides the following ports (Figure 2–29):
■Microphone-in, MIC
■Line-in, LINEIN
■Line-out, LINEOUT
These are standard analog audio connectors. Refer to “Audio CODEC” on page 2–5 for a description of the circuitry attached to these connectors.
