ADV7340/ADV7341
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 I
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.
