New interface options arrive so frequently that trying to keep up can feel like drinking water from a fire hose. While data transfer rates are often the first characteristic identified for each interface, it’s important to also note distance capabilities, power requirements, EMI reduction, and cost.<\/p>\n\n\n\n

Which interfaces are we talking about here?<\/h2>\n\n\n\n

This piece is NOT about GigE Vision or Camera Link. Those are both great interfaces suitable for medium to long-haul distances, are well-understood in the industry, and don’t require any new explaining at this point.<\/p>\n\n\n\n

We’re talking about embedded and short-haul interface considerations<\/h2>\n\n\n\n

Before we define and compare the interfaces, what’s the motivation? Declining component costs and rising performance are driving innovative vision applications such as driver assistance cameras and other embedded vision systems. There is “crossover” from formerly specialized technologies into machine vision, with new camera families and capabilities, and it’s worth understanding the options.<\/p>\n\n\n

How shall we get a handle on all this?<\/h2>\n\n\n\n

Each interface has standards committees, manufacturers, volumes of documentation, conferences, and catalogs behind it. One could go deep on any of this. But this is meant to be an introduction and overview, so we take the following approach.<\/p>\n\n\n\n
