Advanced Features Of High Speed Digital I/O Devices: Double Data Rate


As clock speeds and data rates continue to increase, designers of digital integrated circuits are creating new ways to maximize the rate of data being sent into and out of digital devices. One such method is known as double data rate (DDR). With single data rate (SDR) devices, data is latched on either the rising or falling edges of the sample clock. A DDR device latches data on both the rising... » read more

CEO Outlook: Rising Costs, Chiplets, And A Trade War


Semiconductor Engineering sat down to discuss what's changing across the semiconductor industry with Wally Rhines, CEO emeritus at Mentor, a Siemens Business; Jack Harding, president and CEO of eSilicon; John Kibarian, president and CEO of PDF Solutions; and John Chong, vice president of product and business development for Kionix. What follows are excerpts of that discussion, which was held in... » read more

Wrestling With High-Speed SerDes


SerDes has emerged as the primary solution in chips where there is a need for fast data movement and limited I/O, but this technology is becoming significantly more challenging to work with as speeds continue to rise to offset the massive increase in data. A Serializer/Deserializer is used to convert parallel data into serial data, allowing designers to speed up data communication without h... » read more

Delivering High-Speed Communications: The Back Story


Back in January, I posted a blog about what it takes to deliver high-speed communication. In that post, I talked about a new test board for our high-speed 7nm 56G PAM4 & NRZ DSP-based long-reach SerDes. We collaborated with several companies to build a high-precision board that could be used to test our SerDes in a system context. At that time, we were just finishing the opening act for thi... » read more

112G XSR And LR SerDes PHYs


The virtuous cycle of increased computing power enabling new applications which demand more computing power continues unabated. Today, applications spanning AI, autonomous vehicles, video streaming, AR and VR all demand more bandwidth, lower latencies and higher speeds. In response, the SoCs powering the terabit routers and switches at the heart of the network must run even faster. The upgrade ... » read more

Moore’s Law Now Requires Advanced Packaging


Semiconductor Engineering sat down to discuss advanced packaging with Calvin Cheung, vice president of engineering at ASE; Walter Ng, vice president of business management at UMC; Ajay Lalwani, vice president of global manufacturing operations at eSilicon; Vic Kulkarni, vice president and chief strategist in the office of the CTO at ANSYS; and Tien Shiah, senior manager for memory at Samsung. W... » read more

Blog Review: April 3


Synopsys' Taylor Armerding contends that as the IoT becomes more ubiquitous, the threat of cyber-physical attacks is rising, with the potential for a domino effect if even simple devices are compromised in large enough quantities. Mentor's Colin Walls considers the move away from programming on bare metal with the rise of drivers and RTOSes and when it makes sense to still use the old method... » read more

High-Speed Communications: On The Road Again


Lately, we’ve had quite a lot of trade show participation. I discussed ISSCC last month. I will be careful right now to state that ISSCC is a technical conference and not a trade show. The organizers are quite particular about that. Nonetheless, we were invited to demonstrate our high-speed SerDes there, and we got a lot of great questions from a lot of very smart people. Since ISSCC, we... » read more

A Conference For The Ages


The International Solid-State Circuits Conference (ISSCC) was held recently in its permanent location at the San Francisco Marriott Marquis. eSilicon had the honor of both presenting our SerDes capabilities and demonstrating the technology as well. More about that later. First, I’d like to examine the institution called ISSCC. The first ISSCC was held in 1954 in Philadelphia. Yes, 1954, that... » read more

Why 56Gb/s And 112Gb/s SerDes Matter In Our Daily Social-Media-Driven Lives


Hyper-scalers and service providers are moving from 100GbE to 400GbE Ethernet rates and beyond. Wireline and wireless networks are driving new architectures to support the move from 4G LTE to 5G infrastructure. These transitions are driven by the increasing global IP traffic as the world becomes more connected and digital. At the same time, the decentralization of the cloud and data centers are... » read more
