Understanding SerDes Signal Integrity Challenges


Signal integrity (SI) can perhaps best be defined as a set of measures of the quality of electrical signals, which are subject to the effects of noise, distortion and loss. Additional signal integrity issues include jitter, ringing, crosstalk, ground bounce and power supply noise. There are multiple factors that can negatively influence signal integrity, thereby causing errors and system fai... » read more

SerDes Signal Integrity Challenges At 28Gbps And Beyond


After nearly fifty years, NRZ technology continues to pose significant challenges as data rates approach 56Gbps and refreshed standards mandate increased receiver sensitivity (down to 35 mV). With shorter unit intervals and closing eyes, triggering becomes ever more complex and requires enhanced receiver equalization such as continuous-time-linear equalization and decision feedback equalization... » read more

Performance Increasingly Tied To I/O


Speeding up input and output is becoming a cornerstone for improving performance and lowering power in SoCs and ASICs, particularly as scaling processors and adding more cores produce diminishing returns. While processors of all types continue to improve, the rate of improvement is slowing at each new node. Obtaining the expected 30% to 50% boost in performance and lower power no longer can ... » read more

The Challenges Of Designing 28G And 56G SerDes IP


The industry move to 56 Gbps PAM4 is undoubtedly one of the greatest challenges currently facing SerDes IP designers and their customers. To begin with, shifting to 56 Gbps PAM4 immediately causes a loss of 9 dB. While the baud rate is 28 Gbaud, there are now three eyes stacked on top of each other. Nevertheless, there is still demand for 35+ dB reach. This is a significant challenge which requ... » read more

What’s Missing In Advanced Packaging


Even though Moore's Law is running out of steam, there is still a need to increase functional density. Increasingly, this is being done with heterogeneous integration at the package or module level. This is proving harder than it looks. At this point there are no standardized methodologies, and tools often are retrofitted versions of existing tools that don't take into account the challenges... » read more

Chip Advances Play Big Role In Cloud


Semiconductor engineering teams have been collaborating with key players in the data center ecosystem in recent years, resulting in unforeseen and substantial changes in how data centers are architected and built. That includes everything from which boxes, boards, cards and cables go where, to how much it costs to run them. The result is that bedrock communication technology and standards li... » read more

Faster SerDes For More Efficient Data Centers


The evolving data center presents an imposing set of challenges for system architects as Dennard Scaling fades and Moore’s Law wanes. These include an exponential increase in data, shifting architectural bottlenecks and a never-ending demand for higher performance within the same power and thermal envelopes. The Internet of Things (IoT), Big Data analytics, in-memory computing and machine ... » read more

Silicon Photonics Comes Into Focus


Silicon photonics is attracting growing attention and investment as a companion technology to copper wiring inside of data centers, raising new questions about what comes next and when. Light has always been the ultimate standard for speed. It requires less energy to move large quantities of data, generates less heat than electricity, and it can work equally well over long or short distances... » read more

Integration IP Helps IP Integration


You might not know much about the MIPI Alliance if you aren't designing mobile phones, but you will soon. Other application areas are taking interest in what this group has accomplished. The alliance was founded in 2003 to create standards for hardware and software interfaces in mobile devices. Successful examples include a camera serial interface (CSI) and a display serial interface (DSI), ... » read more
