A small amount of on-chip analog-test hardware offers big payoffs when you are dealing with high-speed serial interfaces. As part of the serial-interface IP (intellectual property) or of an IP wrapper ...

High-speed-digital serial I/O links and DDR memory interfaces are presenting significant measurement challenges as fourth-generation standards emerge. As signals travel at ever higher speeds over ...

The storage industry this year began widespread implementation of serial-based technologies to replace parallel physical-interface standards (AT bus attachment, or ATA, and Small Computer Systems ...

At some point, you’ll need to test that interface. Before testing, though, you should consider these five key factors. Practically everything you design these days includes some kind of serial ...

The Joint Test Action Group (JTAG) formed in Europe in the late 1980s. Up until that time, most printed circuit boards (PCBs) were populated with chips that had exposed pins that were soldered through ...
