Product Details

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.

APPLICATIONS
