The latest x1 PCI Express frame grabber from Epix appears to use an Altera Stratix GX with integrated transceivers. The PIXCI E1DB Dual Base Camera Link board interfaces to one or two Base configuration Camera Link cameras at sustained data-transfer rates to 204 Mbytes/s.
“With x4 implementations, there are a relatively even mix of customers using both discrete PHYs and FPGAs and full FPGA implementations,” says Daellenbach, “and for x8 implementations, the majority of customers are using integrated PHYs.” While this may be true in markets other than machine vision, it appears that designers of frame grabbers have taken a somewhat more cautious approach.
