We had a product that had a multiple channels of serial interfaces in the same chip. When we got multiple requests from customers to give them confidence that there is no interference between adjacent channels, specifically when they are simultaneously operating at different frequencies. We had to invent the measurement methodology since there were no specific techiniques to estimate the crosstalk and its impact on serial interfaces. The measurement methodology we came up with is the featured article in Planet Analog today. Thanks to Jeff Hushley for making the measurements and writing the article. The article can be found at
