The ZeusCORE Xtra-Long-Reach (XLR) Multi-Standard-Serdes (MSS) IP 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 Gen1-6 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.

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.

High speed A/D

The ZeusCORE MSS IP employs a high speed A/D architecture that has configurability for both the A/D sampling rate as well as the A/D resolution

Sub-sampling clock multiplier

The ZeusCORE CDR employs a wide tuning, sub-samplingclock multiplier that can track over 5000ppm error for both scrambled and 8B/10B encoded data

Master controller

The ZeusCORE DSP Master Controller includes:

  • All required training is integrated, without the need of external RAM
  • Non-destructive eye monitoring
  • 1+D Partial Response Coding
