Rambus has officially announced the 112G Long Reach (LR) SerDes PHY. Hemant Dhulla, VP and GM of IP Cores, said, “By leveraging leading 7nm process technology, Rambus is enabling the next generation of communications and data center applications.”
He further stated, “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.”
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 center and network applications, doubling the data rate of 56G SerDes.
Rambus is at the forefront of implementing 112G design to address the long-reach backplane requirements for next-generation data-intensive applications. Those applications include generation terabit switches, routers, optical transport networks (OTNs), and high-performance networking equipment.
The new Rambus 112G LR SerDes 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.
The 112G LR SerDes PHY uses both PAM4 and NRZ (PAM2) signaling to provide reliable operation across a broad range of data rates. As such, they support legacy protocols, and provide the scalability to achieve the highest levels of performance.
They are built on a configurable architecture, enabling power to be matched to the channel loss. An embedded micro-processor enables firmware-controlled PMA configuration, initialization and adaption for maximum flexibility with minimum SoC integration effort.
The 112G LR SerDes PHY also provides SoC and system designers two other key features. Its DSP-based architecture hands them improved signal to noise (SNR) and extended reach. Plus, the 112G is configurable to provide power, performance, and area (PPA) optimization for medium reach (MR) and long reach (LR) applications.
This latest portfolio addition highlights Rambus leadership in high-speed SerDes PHY IP, leveraging the company’s long tradition of signal and power integrity expertise — remaining at the forefront of innovation in interface technology.
