I am looking to replace the Epson S2D13P04 multi camera IC in a design. This part supports various video modes, one of them called 'merge mode' which resizes all 4x video inputs and formats them into one frame.We were initially looking at the ADV7281 chip, however we noticed it does not seem to support a similar merge mode. This feature is important to the design. If this is not supported, are there other parts that might include this feature with 4x analog camera inputs and one MIPI CSI-2 output?
The Epson part has 4 input decoders so it can decode 4 streams at the same time. The ADV7281 can only decode one stream at a time. Therefore the 7281 cannot merge 4 streams into one stream. ADI has no simultaneous multiple decoders in one device.
