Rambus has launched a 28Gbps multi-modal serial link PHY on Samsung’s leading-edge 14nm Low Power Plus (LPP) process.

According to Luc Seraphin, senior VP and GM of Rambus’ Memory and Interfaces division, the R+ 28G Serial Link PHY is a100 Gigabit Ethernet solution optimized for power and area efficiency in long-reach channels.


“The increasing demand for more data at increasing speeds continues to drive the bandwidth requirements in enterprise applications,” Seraphin explained. “We are pleased Samsung has selected us to work in their advanced 14nm LPP process, enabling our solutions to achieve the tremendous speeds and power efficiencies required by today’s high-performance systems.”

Key R+ 28G Serial Link PHY features include:

  • High-performance and multi-protocol compatibility with support for data rates ranging from 1.25Gbps to 28.1Gbps – across copper and backplane channels with up to 30dB loss in a wide range of industry-standard interconnect protocols.
  • Application-specific optimization enabled by efficient and scalable architecture with adaptive and programmable receive equalization; as well as support for transmit FIR adaptation.
  • Ease-of-integration and bring-up featuring built-in-self-test (BIST) with PRBS generator and checker, in-situ real-time monitoring and support for LabStation™ Validation Platform.

It should be noted that Rambus’ R+ industry-standard interface solutions are high-quality, complete PHY solutions designed with a system-oriented approach – maximizing flexibility in today’s most challenging system environments.
