Component Specifications

Definition
A specialized integrated circuit (IC) that serves as the central processing unit of a Network Interface Card (NIC), responsible for managing data transmission, receiving packets, implementing network protocols (e.g., Ethernet, TCP/IP), handling error correction, and interfacing with the host system's bus (e.g., PCIe). It optimizes network performance through hardware acceleration and reduces CPU load.
Working Principle
Operates by receiving digital signals from the network medium via the PHY (physical layer) chip, decoding packets according to network protocols, performing data buffering and flow control, and transferring processed data to the host system memory via direct memory access (DMA). It manages interrupts, prioritizes traffic, and implements security features like encryption offloading.
Materials
Semiconductor silicon wafer with copper interconnects, packaged in plastic quad flat pack (PQFP) or ball grid array (BGA) with gold or tin-lead solder balls. Dielectric materials include silicon dioxide and polyimide.
Technical Parameters
  • Data Rate 1 Gbps to 100 Gbps
  • Package Type BGA-256
  • Bus Interface PCIe 3.0/4.0
  • Power Consumption 1.5W to 10W
  • Operating Temperature -40°C to 85°C
Standards
ISO/IEC 11801, IEEE 802.3, PCI-SIG PCIe
