So you just want a de-embedder and AoIP output?
Dante will cause you problems because Audinate keep some bits closed, but AES67 should be workable (Or ST2110-30, pretty much the same thing), and AES67 will interrop with Dante in at least some Brooklyn II versions.
For 3G-SDI stuff something like an Artex-7 is a good fit, having the transceivers you will need, and Yea, Semtech or TI for the line equalisers.
The elephant in the room with that project is clocking, because unless the SDI and PTP clocks are locked to the same reference you will need an ASRC core in there to avoid glitches. Also on the subject of clocking make sure you connect a suitable clock generator for the transceivers and SDI processing, 148.5MHz and 148.35MHz are the conventional choices for 274M video, SIlabs parts are the common answer.
