Synopsys is Paving the Way for Success with 112G SerDes and Beyond

Data communication speeds continue to grow. New encoding schemes, such as PAM-4 are helping achieve faster throughput. Compared to the traditional NRZ scheme, PAM4 can send twice the signal by using four levels vs. the two used in NRZ. The diagram at the top of this post shows the how data density is increased. With progress comes… Read More

When Implementing 112G PAM4 Channels Getting There is Half the Fun

The slogan in the title of this post originated with the cruise ship industry in the 1950s. The comment resonated then, and it continues to do so now. In a different context of course. Consider the substantial pressure for higher bandwidth channels. 5G has lit the fuse on a massive increase in wireless data volumes. IoT, autonomous… Read More

High-speed communication is a critical component for many applications, most notably in the data center. The serializer/deserializer physical interface, or SerDes PHY is the backbone of many different forms of high-speed communication for this application. Use cases include on chip, between chips, between boards and racks… Read More

This session will open the DAC IP Track at 10:30 on Monday “How PAM4 and DSP Enable 112G SerDes Design” in Room N264. I am very proud to chair this invited paper session, as it addresses one of the key pieces of design, enabling to exchange data flow at the highest possible data rate. It can be between two chips on the same board, we talk … Read More


400G Ethernet test chip tapes-out at 7nm from eSilicon

400G Ethernet test chip tapes-out at 7nm from eSilicon
by Tom Simon on 05-24-2019 at 10:00 am

Since the beginning of May eSilicon has announced the tape-out of three TSMC 7nm test chips. The first of these, a 7nm 400G Ethernet Gearbox/Retimer design, caught my eye and I followed up with Hugh Durdan, their vice president of strategy and products, to learn more about it. Rather than just respin their 56G SerDes, they decided… Read More
