Company recently a project need to design into 1 out of 4 SDI matrix, chose at the crossroads of ADI ADN4600 digital chip,

Test found that more than 1080 p @ 30 hz (1080 and 1080 p I @ 50, 60 hz) video image output backend cannot identify, 1080 I was a bit better, a video image output, but there will be lose some images, 1080 p @ less than 50, 60 full recognition,

But there is a strange phenomenon, I use the pens and measuring the input terminal of the oscillograph, clip shielding layer (ground), 1080 p @ 50, 60 hz signal can be output, but the picture is not stable,

A headache, now have no direction, I hope you can instruct me,

Excuse me:
Have a mature SDI or matrix switching chip solutions can be used, don't use FPGA to handle,

All the parts to jilt came in, I hope everybody can guide!!!!!!
