ADV7340/ADV7341

Rev. C | Page 5 of 108

GENERAL DESCRIPTION

The ADV7340/ADV7341 are high speed, digital-to-analog

video encoders in a 64-lead LQFP package. Six high speed,

NSV, 3.3 V, 12-bit video DACs provide support for composite

(CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog

outputs in standard definition (SD), enhanced definition (ED),

or high definition (HD) video formats.

The ADV7340/ADV7341 have a 30-bit pixel input port that can

be configured in a variety of ways. SD video formats are

supported over an SDR interface, and ED/HD video formats are

supported over SDR and DDR interfaces. Pixel data can be

supplied in either the YCrCb or RGB color space.

The parts also support embedded EAV/SAV timing codes,

external video synchronization signals, and I2C® communication

protocol.

In addition, simultaneous SD and ED/HD input and output are

supported. Full-drive DACs ensure that external output buffering

is not required, while 216 MHz (SD and ED) and 297 MHz

(HD) oversampling ensures that external output filtering is not

required.

Cable detection and DAC autopower-down features keep power

consumption to a minimum.

Table 1 lists the video standards directly supported by the

ADV7340/ADV7341.
