Description
AI
TheADV7390/ADV7391/ADV7392/ ADV7393 are a family of high speed, digital-to-analog video encoders on single monolithic chips. Three 2.7 V/3.3 V, 10-bit video DACs (a single DAC for the WLCSP package) provide support for composite (CVBS), S-Video (Y-C), or component (YPrPb/RGB) analog outputs in either standard definition (SD) or high definition (HD) video formats. The single DAC WLCSP package supports CVBS (NTSC and PAL) output only in SD resolution (see Table 2).Optimized for low power operation, occupying a minimal footprint, and requiring few external components, these encoders are ideally suited to portable and power-sensitive applications requiring TV-out functionality. Cable detection and DAC auto power-down features ensure that power consumption is kept to a minimum.The ADV7390 / ADV7391 have an 8-bit video input port that supports SD video formats over an SDR interface and HD video formats over a DDR interface. The ADV7392 / ADV7393 have a 16-bit video input port that can be configured in a variety of ways. SD RGB input is supported.All members of the family support embedded EAV/SAV timing codes, external video synchronization signals, and the I2C®and communication protocol. Table 1 and Table 2 list the video standards directly supported by the ADV7390/ADV7391/ ADV7392/ADV7393 family.APPLICATIONSMobile handsetsDigital still camerasPortable media and DVD playersPortable game consolesDigital camcordersSet-top box (STB)Automotive infotainment (ADV7392andADV7393only)
