My first Tech Blog – Measuring BER for serial links
Posted by palanis on February 3, 2007
One of our customers once asked me, how to measure BER for a serial NRZ data communication link with clock and data recovery. It turns out that bit errors are caused due to multiple reasons, mostly random. Moreover, even though one has a way to detect and count the number of errors over a given period of time how can one predict the future BER given the random nature of errors. Given such a scenario how can one reliably measure the BER of a link. The result of the research I did to answer this question was a technical article:

Hi Palani,
I’ve been scouring the Web for other sites talking about high speed interconnect issues. Haven’t seen much out there yet. Good to find you. I will check in from time to time both to find out what’s going on in the tech side of your brain as well as to hear about your travels. –rbm
