MaxLinear has unveiled the Annapurna 224G scale-up retimer, which enables copper connectivity in AI data centers at 224Gbps per lane, achieving up to 1.6Tbps of bandwidth. The device uses PAM4 signaling and advanced signal processing techniques to overcome physical constraints of copper channels, making it viable for large-scale GPU fabrics.

Annapurna supports both eight-lane and sixteen-lane configurations and offers ultra-low latency and high power efficiency. Expected availability is in Q2 2026. The market for AEC and on-board retimers is anticipated to reach 30 million units by 2029, presenting a significant growth opportunity for MaxLinear.
