Litrinium’s linear chipsets are purpose-built for LPO and CPO architectures, delivering exceptional dynamic range, superior signal integrity, and industry-leading power efficiency. These capabilities are critical for AI-scale interconnects and enable high-density GPU cluster topologies for next-generation data center infrastructure.

Equalizers

and Cable Drivers

Litrinium’s equalizers and cable drivers enable robust, low-latency transmission over copper interconnects, critical for AI infrastructure. As data centers scale with higher bandwidth and dense GPU deployments, they preserve signal integrity and consistent performance across complex, high-speed channels.

Clock and Data Recovery (CDRs)

Litrinium’s CDRs and retimers deliver the precision and performance required for high-speed AI data center connectivity. By restoring timing accuracy and reconditioning signals, they ensure clean, low-jitter links across optical and copper interconnects, enabling scalable, high-fidelity next-generation infrastructure.

PCIe Equalizers

and Retimers

Litrinium’s PCIe equalizers and retimers deliver signal integrity and scalability for AI data centers. Supporting PCIe 6.0/7.0 and 100G+ lane speeds, they ensure low-latency, reliable transmission across dense GPU clusters, enabling seamless performance in next-generation compute fabrics.

Optimizing AI Infrastructure with Ultra-Low-Power Connectivity

At Litrinium, we view analog design as both art and science. As a company focused exclusively on solving the connectivity challenges of modern AI infrastructure, we develop technologies that keep pace with the rapid evolution of data center networking.

Advanced Signal Integrity

Litrinium emphasizes ultra-low noise and high linearity, which are critical for maintaining signal fidelity at high data rates across optical and copper links.

Breakthrough Power Efficiency

Litrinium was founded on a commitment to minimizing power consumption, helping data centers manage thermal budgets as bandwidth and system scale continue to grow.
