High speed digital data communications demand

It appears to the author, that the high speed data communications sector of the market is growing fast. At least this is the conclusion that we must draw from the demands on our design resources from various customers.

USB3, 10G, HDMI, etc are all very demanding in terms of the semiconductor processes to be used ( cost effectively ), design techniques, systems engineering, CAD tools, availability of parameterics of cables, connectors, PCB based information and ultimately design techniques to stitch all of these together into a device or subsystem that will actually work in the real world.

As we work through these designs, we find that there is a vast gap between theory and reality. This includes simulations also. This has always been true in some degree with other technologies but in the case of these designs it becomes critical. Designing the devices to operate robustly in the real world is very time consuming and in many ways an art, rather than a science. Design experience is called for more than anything to implement these techniques from an intuitive point of view. We believe this is going to be a most interesting and challenging series of designs. More as the work proceeds.
