Overview
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: 10-224Gb/s long-reach multi-standard optical and electrical SerDes for Ethernet applications and Ultra Accelerator Link (UALink)
- Optical IM-DD: 50-224Gbps optical optimized SerDes with MLSD for data center applications
- PCIe7/CXL: 1-128Gb/s PCIe Gen1 – Gen7 long-reach electrical SerDes
- CPO/NPO: power optimized 50-224Gb/s medium reach (MR/VSR) electrical SerDes for emerging CPO/NPO applications
- Coherent Lite: Coherent DSP optical optimized SerDes for data center applications
Key Features
Protocol Features (ANLT, LLPD)
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.
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.
Flexible D/A
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.
Master controller
The AthenaCORE DSP Master Controller includes:
- All required training is integrated, without the need of external RAM
- Non-destructive eye monitoring
- 1+D Partial Response Coding
Benefits
- Receive Equalization
- 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.
- Output Driver Voltage
- Programmable 400 – 1200 mVdiff-pkpk (inner eye)
- Optional Optical Non-Linearity Correction Features
