Today’s designers face a multitude of problems when tryingto move data within their systems. These problems rangefrom overtaxed parallel-bus bandwidth to a lack of pins at thecard edge connector. Even routing parallel buses around today’sdense circuit boards is very difficult. This applicationnote discusses using high-performance serial links as a solutionto some of these bottlenecks. A serial approach providesthree immediate benefits: first, bandwidth may be off-loadedfrom the backplane bus; second, connector pins are saved;and, third, circuit board routing is made much easier sinceonly one or two traces have to be routed for the data path(versus one for each data bus bit plus a separate clock).
