Not a short list: High-speed backplane design considerations News & Analysis 10/14/2003 Post a comment A new generation of backplanes is emerging that achieve 5 to 10 GBits/s signal speeds, and even higher speeds are on the horizon. In this paper, adopted from the recent Communications Design Conference, a Flextronics engineer - an old hand at high-speed board design - discusses the design tradeoffs, materials, connectors, transmission line and signal integrity effects necessary to finding workable board and backplane solutions.
Backplane health rests on fault finding News & Analysis 10/10/2003 Post a comment Backplanes and motherboards responsible for delivering and distributing power to multiple card systems must be immune to individual card failures that could jeopardize reliable system operation.
'Rail-to-rail' for HDTV/RGB Product News 10/10/2003 Post a comment Intersil Corp. is aiming two triple rail-to-rail amplifiers at high-definition digital television and high-speed RGB monitor applications that require low power consumption.
Programmable clock regeneration techniques get signals through extreme conditions News & Analysis 10/8/2003 Post a comment Blaming the victim? Blaming the clock for system failure is easy, but what are the root causes? Does the problem originate from the clock or is the clock a victim of the surrounding environment? While this article cannot attempt to answer all system specifics, Cypress' David Green does look at the methods of attenuating jitter in the presence of dirty clock reference sources. He explores redundant clocking architectures, and examines some logic-level filter produces that help attenuate jitter.
EMI from the Ground Up: Maxwell to CISPR News & Analysis 10/7/2003 Post a comment Sooner or later, every power supply designer finds this out for himself --- that if anything has the potential to cause a return to the drawing board at the very last moment, it is either a thermal issue, a safety related issue, or a stubborn EMI problem, says National Semiconductor's Sanjaya Maniktala, in the introduction to this multi-part series on EMI effects. In Part 1, here, Sanjaya offers insights into the European and ISO standards that mandate analysis of board level signals. Part 2 sho
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
