AI High-Speed Connectivity Chips: The Four-Way Battle Between MRVL, CRDO, MXL & ALAB
The AI data center buildout is reshaping connectivity chip markets. Marvell dominates optical interconnect, Credo owns active electrical cables, MaxLinear challenges in PAM4 DSP, and Astera Labs holds a PCIe moat. This industry overview maps all four competitive layers.
MaxLinear (MXL) 深度研究：光學 DSP 黑馬，能否在 1.6T 時代守住灘頭？
MaxLinear 正從邊緣化寬頻晶片廠完成向 AI 光互連的蛻變。Keystone PAM4 DSP 已贏得超大規模資料中心設計勝出，Q1 2026 基礎設施業務年增 136%。但 1.6T 時代的 Rushmore 追逐戰仍是最大變數——估值合理（NTM EV/Revenue 8x），積極觀望是當前最佳策略。
MaxLinear (MXL) Deep Research: DSP Dark Horse — Can It Hold Ground in the 1.6T Era?
MaxLinear pivots from broadband to AI optical interconnect. Keystone PAM4 DSP secured hyperscale design wins, lifting Infrastructure revenue 136% YoY in Q1 2026. The 1.6T era test: Can Rushmore outpace Marvell and Broadcom? Valuation ~8x NTM EV/Revenue; execution risk is high.
