System, PCB, & Package Design : BoardSurfers: Three Steps to Using Embedded Components

mrigashira

If you think embedding components in a PCB just reduces product size, well that's true but that's only half the truth. Embedding components also increases performance and reduces transmission loss. So it's about miniaturization and performance with e...

Verification: Catching up with Higher Ethernet Speed: VIP Supports 802.3ck

Dave Huang

Draft 1.0 of 802.3ck, also known as 100G per lane, was finally published by IEEE in Dec 2019. This draft provided the standardization of higher lane speed support for backplane systems, including 3 speed mode variations: 100G, 200G, and 400G. Backplane Ethernet speed is increasing, evolving from 10G, 25G, 50G, to current 100G on a single SerDes lane within less than 10 years, offering unprecedented capacity for the datacenter…

Verification: Sizing Up eUSB2 Verification

Dave Huang

USB is one of the most widely used interfaces in the PC market for more than 20 years. Though it remains the same form in laptops and servers, it never stops its evolution in terms of capacity and speed. Embedded USB2.0, known as eUSB2, was created to address the concerns of power efficiency and portability. Although eUSB2 largely reuses USB2.0 protocol layer, the verification of eUSB2 can be never thought of as a miniature…

Verification: Why Is the Evolving HBM3 Such a Revolutionary Technology and How Can You Be Ready for It?

Thierry Berdah

Since 2013, we have seen the HBM specifications being released by JEDEC and companies announcing in the same month HBM products just like magic. How can these companies have a silicon-proven product altogether with newly announced official specifications? What is the secret process they use in order to be constantly first-in-market with these new technologies? And more important, what can YOU do in order to also be such…
