Breakthrough CMOS device built on TeraSignal’s TSAFE™ analog front-end architecture integrates CMIS-based link training with Advanced Equalization to dramatically improve link margin, reach, and reliability in AI Scale-Up Networks
Los Angeles, Calif., March 17, 2026 – OFC 2026 – TeraSignal, a leader in intelligent interconnect technology today announced the TeraSignal TS5802, the world’s most advanced analog equalizer, implemented in advanced CMOS technology and engineered to extend reach and increase link margin for 200G and higher-speed interconnects. The TS5802 is built on TeraSignal’s proprietary TSAFE™ (TeraSignal Analog Front-End) technology, which tightly integrates the critical high-speed analog building blocks required for next-generation linear interconnects in AI scale up networks.
In addition, the TeraSignal TS5802 utilizes TeraSignal’s TSLink™ technology to perform CMIS (Common Management Interface Specification) based link training and monitoring, enabling intelligent, adaptive operation that automatically optimizes link performance across a wide range of channel conditions. Link training allows the device to automatically configure its equalization and operating parameters for a given link, while link monitoring provides real-time telemetry needed to detect degradation and prevent failures before they impact system performance.
As data rates accelerate toward 200G, 400G, and beyond, traditional analog equalization approaches based on CTLE (Continuous Time Linear Equalizer) are increasingly strained by channel loss, crosstalk, and noise. TSAFE addresses these challenges through a tightly integrated analog architecture that combines a low-noise linear amplifier, CTLE, FFE (Feed Forward Equalizer), and linear output driver into a single optimized signal path. By combining both CTLE and FFE functions, TS5802 is the first analog equalizer in the industry that is able to reduce both pre-cursor and post cursor ISI (inter-symbol interference) terms, resulting in longer reach and improved reliability for demanding 200G+ applications. Implemented in CMOS, the TS5802 delivers this level of performance while enabling high levels of integration, scalability, and cost efficiency.
“TS5802 represents a major leap in analog signal conditioning for high-speed linear interconnects,” said Dr. Armond Hairapetian, CEO at TeraSignal. “By integrating TSAFE and CMIS-based link training into a single CMOS device, we enable system designers to achieve significantly higher link margin, lower bit error rates, and reliable operation at 200G and above”.
The TS5802 is optimized for next-generation AI accelerators, hyperscale data center switches, network interface cards, optical modules, and active copper cables, as well as emerging architectures including Active Copper Cables (ACC), Near-Packaged Optics (NPO), Co-Package Optics, Linear Pluggable Optics (LPO) and Linear Receive Optics (LRO).
Its advanced equalization, linear output capability, and intelligent link training and diagnostics allow designers to compensate for severe channel impairments while maintaining excellent linearity and low noise, making it ideal for PAM4-based links and other multi-level modulation schemes.
