Power efficiency for SoCs in data-intensive applications

As the industry rapidly transitions to 400GB and 800GB wired communication applications, 112G is a key building block necessary to support the ever-growing demand for more bandwidth in data centre and network applications, doubling the data rate of 56G SerDes.

Rambus aims to be at the forefront of implementing 112G design to address the long-reach backplane requirements for next-generation data-intensive applications.

This high-speed PHY provides the optimal combination of power efficiency, performance and area, adding to Rambus’ leading-edge large portfolio of silicon-proven intellectual property (IP), design tools and reference flows. With the introduction of 112G, this technology achieves higher performance to rapidly enable industry infrastructure for the 400GB and 800GB applications. 

“By leveraging leading 7nm process technology, Rambus is enabling the next generation of Communications and Data Centre applications,” said Hemant Dhulla, VP and GM of IP Cores, Rambus. “We’re excited to continue to expand our IP portfolio and deliver our customers top-of-the-line performance and flexibility for today’s most challenging systems, including solutions like our 112G LR SerDes PHY.”

The Rambus 112G LR SerDes PHY aims to deliver enterprise-class performance across the demanding backplane environments beyond 30dB. To achieve this data rate requires an innovative SerDes architecture approach to meet the ever-growing data needs for high-speed data-intensive applications. 

Features of the Rambus 112G LR SerDes PHY:

• Scalable ADC-based (analog-to-digital converter) architecture with support for PAM-4 and NRZ signalling.
• DSP-based architecture for improved signal to noise ratio (SNR) and extended reach.
• Configurable to provide power, performance and area (PPA) optimisation for medium reach (MR) and long reach (LR) applications.

The Rambus 112G LR SerDes PHY is currently available for licensing and early access design customers can engage today.

With a near-term roadmap featuring industry-leading 112G solutions for extreme short reach (XSR), the Rambus industry-standard interface offerings are high-quality, complete PHY solutions designed with a system-oriented approach to maximise flexibility in today’s most challenging system environments.
