Semtech’s DirectEdge™ Portfolio Enables Low-Power 400G/800G AI Data Centers
Complete suite of high-performance 100G/channel Transimpedance Amplifiers (TIAs) and laser drivers optimized for energy-efficient Linear Pluggable Optics (LPO)

Semtech’s DirectEdge™ Portfolio Enables Low-Power 400G/800G AI Data Center
Data center interconnects supporting AI workloads face unprecedented bandwidth requirements while operating under strict power envelopes. According to IDC’s Worldwide Semiannual Artificial Intelligence Infrastructure Tracker, annual spending on AI infrastructure will exceed
“For hyperscalers running AI workloads, power has become a critical business constraint,” said Weiliang Deng, director of signal integrity product marketing at Semtech. “Our DirectEdge portfolio benefits hyperscalers by bringing our industry-leading PMDs to successfully deploy LPO, while also addressing the power imperative by eliminating power-hungry DSPs. Every milliwatt saved in optical interconnects can be redirected to computational resources and we believe our LPO solutions are over
