Networking and NICs

High-speed networking and network interface controllers (NICs) are critical to enabling efficient data flow within and between modern datacenters. Network switches and NICs connect servers, storage and external infrastructure, supporting ever-increasing bandwidth requirements driven by AI, cloud and distributed workloads. As port density and data rates scale, designs must ensure robust power delivery, precise protection and high signal integrity while supporting long communication links and reliable operation in demanding environments.

Design considerations

  • Network switches and NICs connect large numbers of high-speed Ethernet ports, requiring scalable architectures that support high bandwidth density and reliable data flow across the system
  • Power distribution is typically based on 48 V infrastructure, creating the need for efficient conversion to multiple lower voltage rails for switch ASICs, PHYs and interface components
  • Power input protection must address higher voltage levels and system reliability using TVS diodes, eFuses and hot-swap solutions to handle surge events and safe board insertion
  • Power management generates tightly regulated local voltage rails for switch processors and supporting components, often with isolated rails and support for Power over Ethernet (PoE) systems
  • Hot-swappable modules and line cards require controlled inrush current and fault isolation to maintain system uptime and prevent disturbances during insertion and removal
  • High-speed communication interfaces require low-capacitance ESD protection to preserve signal integrity across standards such as Ethernet, while buffers, PHYs and transceivers support long-distance and board-to-board communication
  • Signal processing and monitoring functions rely on analog components such as op amps, switches and multiplexers to handle airflow, temperature sensing and system diagnostics
