5.12 TV Decoder

The DE2-70 board is equipped with two Analog Devices ADV7180 TV decoder chips. The
ADV7180 is an integrated video decoder that automatically detects and converts a standard analog
baseband television signal (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
security/surveillance cameras.
The registers in both of the TV decoders can be programmed by a serial I2C bus, which is
connected to the Cyclone II FPGA as indicated in Figure 5.18. Note that the I2C address of the TV
decoder 1(U11) and TV decoder 2(U12) are 0x40 and 0x42 respectively. The pin assignments are
listed in Table 5.16. Detailed information on the ADV7180 is available on the manufacturer's web
site, or in the Datasheet/TV Decoder folder on the DE2-70 System CD-ROM.
