Semtech's 224G Chips Cement Its AI Data Center Play

Semtech is pushing into AI infrastructure with 224G optical chips that could make it a key player in high-speed data center interconnects.

Semtech (SMTC) isn't just sitting on the sidelines of the AI buildout. The company's 224G optical chips are positioning it right in the middle of one of the hottest infrastructure battles in tech — high-speed data center interconnects. If you're watching where AI money actually flows beyond the Nvidias of the world, this is the kind of name worth tracking.

Data centers feeding large language models and AI workloads need insane bandwidth between chips, racks, and servers. That's where optical interconnects come in, and faster standards like 224G are becoming the baseline for next-gen deployments. Semtech's push into this space means it's competing for design wins inside the facilities that hyperscalers are pouring billions into right now.

The tradeable angle here is simple: Semtech has historically been known for its LoRa IoT technology, but the optical networking segment is increasingly the growth engine investors should watch. A successful ramp of 224G products could meaningfully shift how the Street values this company — and that repricing hasn't fully happened yet.

Of course, execution risk is real. Semtech has had its share of turbulence over the past few years, including challenges tied to its CML Microsystems acquisition. But if AI capex spending holds — and every signal from hyperscalers says it will — demand for high-performance optical silicon should provide a durable tailwind for SMTC heading into the next product cycle.
