Semtech CorporationSemtech launches new 224G TIA and driver portfolio for NPO/CPO, advancing its product line for AI data centers.

Semtech Corporation has introduced a family of 224G linear Transimpedance Amplifier (TIA) and driver solutions designed to accelerate deployment of Near-Packaged Optics (NPO) and Co-Packaged Optics (CPO) architectures for AI clusters and hyperscale data centers. The new portfolio includes the GN1838L and GN42T380, which the company calls the industry's first linear octal TIAs, and the GN42M380 linear octal Mach-Zehnder Modulator driver, optimized for 1.6T, 3.2T, 6.4T, and 12.8T optical engines. These products target CEI-224G-Linear and Open CPX interfaces, addressing power, thermal, and signal integrity challenges in AI back-end networks. Semtech will showcase the portfolio at CIOE 2026 in Shenzhen, China, from September 9-11.
