The UltraAthenaCORE Extended Long-Reach (XLR) Multi Standard SerDes (MSS) IP is a high-performance, area and latency optimized, DSP-based PHY. It is a highly configurable IP that supports all leading edge NRZ and PAM data center standards from 10 Gbps to 224 Gbps, supporting diverse protocols such as 10/25/50/100/200 Gbps Ethernet and UALink.
UltraAthenaCORE leverages high- performance A/D converters to digitize incoming data over copper or fiber. UltraAthenaCORE Master Controller uses patented signal processing techniques to recover the signal, while optimizing both power and latency.
UltraAthenaCORE includes protocol features critical in next generation technologies: ANLT (802.3 AutoNegotiation, Link Training) and PCIe-critical low-latency phase detector, fast rate changes and low power modes.
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 UltraAthenaCORE MSS IP has options for a standard long reach swing, a high swing driver for optical applications, and a short reach optimized driver to optimize PPA.
The AthenaCORE DSP Master Controller includes:
Designed for closed eye, backplane systems greater than 45db of insertion loss at Nyquist (53GHz) for PAM4 with high MLSD. Includes blind adaptive equalizer and channel estimator.
Programmable 400 – 1200 mVdiff-pkpk (inner eye)
Optional Optical Non-Linearity Correction Features
