The Rambus 16G Multi-protocol SerDes (MPS) PHYs are a high-performance serial link subsystem. Optimized for power and area in challenging, high-loss channels typical of copper backplanes and long runs of cable, our 16G MPS PHYs are ideal for networking, telecom and data center systems.
The PHYs come complete with a PMA hard macro that supports a broad range of protocols and a PCS soft macro for PCIe that is PIPE4.2 compliant. They have a minimal set of broadside control and are configurable in x2, x4 and x8 lane configurations. This gives the PHYs improved flexibility and support for a wide range of applications.
In order to improve system margin and performance, our solution features transmit and receive equalization, data rate negotiation, and equalization adaptation. This ensures that data is recovered even in the presence of channel and system interference.
Available on TSMC, Global Foundry and Samsung process nodes.
Maintaining signal integrity has become increasingly difficult as data rates moves past 28Gbps to 56Gbps and beyond. Up to 28Gbps rates, NRZ is the preferred and standardized encoding scheme which consists of 1’s and 0’s. NRZ is also referred to as PAM2 (pulse amplitude modulation, 2-level), due to its two amplitude levels which contain 1 bit of information in every symbol. With serial data rates hitting 56 Gb/s per channel, signal impairments caused by increased bandwidth has prompted the high-speed serial data industry to adopt PAM4, or 4-level pulse amplitude modulation.
