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 (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 I2 C® and communication protocol. Table 1 and Table 2 list the video standards directly supported by the ADV7390 / ADV7391 / ADV7392 / ADV7393 family.

Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
Evaluation Kits (1)
Analog Devices has developed a 2 piece modular system to evaluate the ADV7390, ADV7391, ADV7392, ADV7393 Encoders.
The 2 piece system consists of a front end board featuring an ADV7403 Analog Devices Multiformat decoder, Cypress USB microcontroller and a Xilinx Spartan 3 FPGA. This board provides data to be sent to Encoder board plugged in to the back end.
Features & BenefitsThe back end plug-in module features the encoder of choice.The form factor of these plug in-modules emphasize the small form factor of this range of video Encoders. The plug-in modules are listed here and are orderable below:
Tools & Simulations
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
