56. 112. 224. SI/PI!
For a lot of Americans, that sounds like the pre-snap play call or audible of a quarterback in North American-style football games. After watching football Thursday, Friday, Saturday and Sunday, that’s where my brain is as well.
However, for those of us in the high-speed connectivity industry, those numbers refer to the speed markers in channel data rates we work with everyday. An embedded engineer implementing a 56 Gbps PAM4 transceiver design. A mechanical engineer may be redesigning a 112 Gbps PAM4 mezzanine connector. An optical engineer is trying to lower current draw on his laser to extend component life.

These are but a few examples. From a signal integrity standpoint, electrical engineers are increasingly challenged to implement these bleeding edge speeds. What help does Samtec offer to educate and support the engineering community with their SI needs?
