ADV7391WB-3 Product Details

The ADV7390/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 digital-to-analog converters (DACs) 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.

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 automatic power-down features ensure that power consumption is kept to a minimum.

The ADV7390/ADV7391WB-3 have an 8-bit video input port that supports SD video formats over a software defined radio (SDR) interface and HD video formats over a double data rate (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 communication protocol.
