ADV7390: Low Power, Chip Scale 10-Bit SD/HD Video Encoder
Product Description
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 DACs provide support for composite (CVBS), S-Video (YC), 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 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 a 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 SPI communication protocols.
