ZeusCORE XLR MSS

The ZeusCORE Xtra-Long-Reach (XLR) Multi-Standard-Serdes (MSS) IP is the highest performance SerDes in the Alphawave IP product portfolio. It is a highly configurable IP that supports all leading edge NRZ and PAM data center standards from 1Gbps to 112Gbps, supporting diverse protocols such as PCI-Express Gen1-5 and 1G/10G/25G/50G/100Gbps Ethernet.

What differentiates ZeusCORE is the addition of a Most Likely Sequence Detector (MLSD) that significantly extends the channel reach performance. This extends the system solution space for customers with the most challenging channels.

IP Subsystem

Most Likely Sequence Detector (MLSD)

MLSD uses Viterbi Detection to make slicing decisions based on a sequence of data symbols. MLSD minimizes decision error across a sequence of symbols and improves the Signal-to-Noise Ratio and Bit Error Rate of systems.
