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 1 Gbps to 112 Gbps, supporting diverse protocols such as PCI-Express 6.0 (2.5/5/8/16/32/64 GT/s) and Ethernet (1G/10G/25G/50G/100/200 Gbps).
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.
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.
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.
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
The ZeusCORE DSP Master Controller includes:
Designed for closed eye, backplane systems greater then 40db of insertion loss at Nyquist for PAM4 with high MLSD. Includes blind adaptive equalizer and channel estimator.
