Is it possible to have the LMH1297 drive one BNC from an input 100-ohm diff pair and receive an SDI feed on the second BNC then send this over the output 100-ohm diff pair? Right now the only description of using the 2nd BNC (SDI_OUT+/-) from an IN0+/- signals is as a secondary output in addition to the primary output (dual cable driver mode). My use case would allow me to have a my 2nd BNC (SDI_OUT+/-) either be an FPGA driven output OR a loop through of the input for ultra-low latency direct video viewing. The main idea here would be that I could change an output from my design from a processed to a raw video feed via a software command.
Use 1 : FPGA driven output
Use 2: Loop through video
Thanks!
