If signal integrity engineers had the power to make their jobs as easy as possible, every signal in an electronic device would have its own coaxial cable to connect driver to transmitter. But then electronics would be the size of buildings again and certainly wouldn’t fit in your pocket. So instead, we try to cram as much stuff as possible onto a little PCB and make it work at 100s and 1000s … Read More
When trying to design SERDES signals on board, designers often receive recommendations on placing stitching vias around differential signal vias of a channel. The purpose is to provide continuous return current path when signals switch layers, so that the discontinuity of trace impedance can be minimized.
Because of the increasing board density, the issues designers are facing by following this recommendation … Read More
