GENERAL 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.
