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.

Astera Labs (ALAB) 深度研究：AI 連接神經系統的壟斷者，還是估值已提前透支？

Astera Labs（ALAB）是 AI 基礎設施連接晶片市場中護城河最清晰的純玩家。PCIe 6.0 Retimer 佔市場逾 50%，76% 毛利率零負債，Q1 2026 年增 93%。Scorpio Scale-up Switch 開啟第二成長曲線，但 20x+ NTM EV/Rev 估值已充分定價。四道濾網評級：放行但等待。

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。

Credo Technology (CRDO) 深度研究：銅軸縫隙霸主買下「光替代品」入場券，AI 連接賽道的 M&A 軍備競賽

CRDO 是 AI 資料中心銅軸短距互連的事實壟斷者，FY26 營收三倍、毛利 68.6%、零負債。但 AEC 物理極限與 Marvell 競爭壓頂。2026/4 以 13 億美元收購 DustPhotonics，買下光通訊入場券——複製 Marvell+Inphi 劇本。整合期錯殺才是真正進場時機。

Credo Technology (CRDO) Deep Research: The AEC King Buys Its "Optical Exit Ticket" — M&A Arms Race in the AI Connectivity Race

CRDO holds 88% AEC share in AI data center interconnect — revenue tripled in FY26, 68.6% gross margin, zero debt. The $1.3B DustPhotonics deal buys its optical exit ticket, replicating the Marvell+Inphi M&A playbook. Integration dislocation is the entry window.

Astera Labs (ALAB) Deep Research: The AI Connectivity Monopolist — or Is Valuation Already Overextended?

Astera Labs (ALAB) holds 50%+ PCIe 6.0 Retimer share, 76% gross margin, zero debt, and 93% YoY growth in Q1 2026. Scorpio Switch targets a $20B Scale-up market — but at 20x+ NTM EV/Rev, valuation has fully priced in success. Four-Filter verdict: Pass but Wait for a better entry.

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.
