Hi,
We're planning on using a DS90UB960-Q1 in a (non critical) medical imaging application to take the FPD-Link III feeds from 4x 1920x1080 PoC cameras all running at 60fps. We require the camera interfaces to be galvanically isolated (from the host PC used in the application, but not from each other), so the current plan is to put the deserializer and an FPGA on the isolated side of our controller, with the FPGA taking the MIPI CSI2 outputs and converting them into a parallel format suitable for sending over a bank of high speed digital isolators. The signals from the isolators will then enter another FPGA where the video streams will be buffered and sent over a PCI Express interface to a host PC.
This is quite an ugly solution as it requires two FPGAs, a fairly wide, high speed bus on the PCB and a large number of isolator devices. I'm wondering, therefore, if there is any practical means by which we can directly galvanically isolate the FPD-Link III interfaces between the cameras and DS90UB960-Q1?
Matt.
