Big changes await disk drive industry
News & Analysis 7/29/2003 Post a comment
The hard-disk drive industry is finally coming to terms with the reality that many of its underlying technologies are approaching their performance limits. Starting this year manufacturers are gearing up to debut faster, more cost-effective, less power-hungry serial technologies to replace parallel SCSI and ATA interfaces.
Managing Loss in High-Speed PCBs
News & Analysis 7/11/2003 Post a comment
As design frequencies increased into the 300-400 MHz range, and especially with the introduction of super-high-speed gigabit-per-second serial signaling, losses in PCB traces suddenly became impossible to ignore. Still, many designers are unsure when loss is really important, what causes
it, how it can be measured, and how to minimize it. This article examines all of these issues.
