Cyclone II DSP Development Board Components
■ J16—an amplified audio connector output for headphones
These jacks connect to the TI TLV320AIC23 stereo audio CODEC (U11),
which controls volume and balance levels and connections. See
“Audio
CODEC Converter (U11)” on page 2–14 .
VGA Output Connector (J21)
J21 is a standard DB-15 VGA video output connector. This connector
interfaces to the Fairchild FMS3818 Triple Video D/A Converter (U21) on
the EP2C70 FPGA. J21 allows video images to be displayed on VGA
monitors.
VGA Triple Video D/A Output Converter (U21)
The Cyclone II DSP development board contains a high density DB-15
connector (U21), which outputs VGA and a triple video D/A output
converter with the following features:
■ 3 x 8 bit, 180 megapixels per second
■ ±2.5% gain matching
■ ±0.5 LSB linearity error
■ Internal bandgap voltage reference
■ Low glitch energy
■ One 3.3-V power supply
Table 2–9 lists the VGA triple video D/A output converter device
reference.
