The DE2-115 board is equipped with an Analog Device ADV7180 TV decoder chip. The ADV7180
is an integrated video decoder that automatically detects and converts a standard analog baseband
television signals (NTSC, PAL, and SECAM) into 4:2:2 component video data compatible with the
8-bit ITU-R BT.656 interface standard. The ADV7180 is compatible with a broad range of video
devices, including DVD players, tape-based sources, broadcast sources, and security/surveillance
cameras.
The registers in the TV decoder can be programmed by a serial I2C bus, which is connected to the
Cyclone IV E FPGA as indicated in
(U6) is 0x40/0x41. The pin assignments are listed in
ADV7180 is available on the manufacturer‟s website, or in the DE2_115_datasheets\TV Decoder
folder on the DE2-115 System CD.
