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.

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

Getting Ready for 32 GT/s PCIe 5.0 Designs


The transition from older PCI Express (PCIe) technologies to the latest Revision 5.0 is on an accelerated path, with system-on-chip (SoC) designers seeing a much faster roll out than they did with PCIe 4.0. The recent release of version 0.9 of the PCIe 5.0 Base Specification locks in the functional changes to the specification, allowing designers to confidently start their designs. With the rap... » read more

PCIe 4.0 Hangs In, PCIe 5.0 Coming On Strong


First introduced in 2003 as a universal serial chip-to-chip interface running at 2.5 Gbps, PCI Express (Peripheral Component Interconnect Express), also known as PCIe, has advanced several revisions with significant improvements to performance and other features with each new generation. Through broad support, backwards compatibility, and a consistent cadence of upgrades that doubled lane sp... » read more

Supercomputers Are For Everyone


Our SerDes world tour continues. This past month, we demonstrated our 7nm 56G long-reach SerDes in Dallas and Israel. In Dallas, our demonstration included error-free operation in 56G PAM4 over a 30dB channel without forward error correction through an eye-popping five-meter cable. Many thanks to our partner Samtec for providing that cable, allowing backplane designers to now “reach beyond th... » read more
