Spartan-3A DSP 3400A Edition User Guide

Chapter 1:
Introduction
R
4.
AC'97 SoundMAX Codec
Analog Devices AD1981B. The device supports 16-bit stereo audio and sampling rates
up to 48 kHz. The sampling rate for recording and playback can also be different.
Table 1-2
defines the pin assignments.
5.
DVI Connector
Used to connect an external video monitor (DVI or VGA) to the Spartan-3A DSP 3400A
Edition board.
Table 1-3
defines the pin assignments.
Note
: The VGA monitor can be connected to the development board with a
DVI-to-VGA adaptor (sold separately).
6.
Display Controller Device
The DVI circuitry uses a Chrontel CH7301C capable of 24-bit color and 1600 ×
1200-pixel resolution. The display controller device drives the digital and analog
signals to the DVI connector (
“5. DVI Connector”
). The display controller device is
controlled through the I
2
C bus.
The DVI connector supports the I
2
C protocol, allowing the development board to read
monitor configuration parameters, which can then be read by the FPGA through the
I
2
C bus. See
“I2C Bus Addressing,” page 42
for detailed information.
