Hi Tommy, I am not aware of any cameras or frame grabbers with FPD Link or GMSL. Camera Link is a industry standard and there are plenty of cameras and frame grabbers available with this interface, however Camera Link HS is limited to Dalsa. You also may want to take a look at CoaXPress, a new standard that is gaining traction rather quickly. CoaXpress supports video, camera control, and power over a single coaxial cable with cable lengths of 40 meters for CXP-6 and 100 meters for CXP-3. An example of the performance that can be achieved is 12megapixels at 180+FPS. FPD Link https://en.wikipedia.org/wiki/FPD-Link Keith
Hi Tommy: FPD-Link is the technology used in Camera Link. This technology sends 4 7:1 serialized data streams + a parallel clock using LVDS levels. Cable skew and data patterns influence distance achieved. Camera Link HS is packet based. The M protocol runs 8b/10b encoding at 3.125 Gbps/lane and achieves a cable bandwidth of 2.1 GByte/s. The X protocol runs at 10.3125 Gbps with scrambling and Forward Error Correction and achieves a data throughput of 1.2 Gbyte/sec per SFP+ connector.
