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.
Xtra-Long-Reach (XLR) Multi-Standard-Serdes (MSS)
Overview
Key Features
- 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-sampling clock multiplier that can track over 5000 ppm 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
- The ZeusCORE DSP Master Controller includes:
