Question
Can I buffer data from two cameras and send to adv2x2 with 2xspeed (2x27MHz /
8bit), can one adv2x2 process these data?
Answer
The input format to the ADV2xx devices is expected to be CCIR656, PAL, NTSC,
SMPTE274M(1080i) or SMPTE296(720p), otherwise custom -specific mode must be
used.
Custom-specific mode allows video input in any interlaced or preogressive
format as long as the input data rate limits are met.
Input data rate limits are listed in the datasheet for your product - ADV202 or
the ADV212 ( see the relevant datasheet for more details.)
