Product Specifications

Technical details and manufacturing context for High-Speed Capture Module

Definition
The High-Speed Capture Module is a critical hardware component within a Multi-Protocol Network Protocol Analyzer. Its primary role is to intercept, timestamp, and buffer raw network data packets from one or more physical interfaces at line rates, enabling deep packet inspection, performance monitoring, and troubleshooting across various network protocols without dropping packets.
Working Principle
The module operates by connecting directly to network taps or SPAN/mirror ports. It uses dedicated high-speed PHY chips and FPGA/ASIC logic to receive electrical/optical signals, perform clock recovery, decode the physical layer, and frame the data into packets. These packets are timestamped with nanosecond precision, buffered in high-speed memory (DDR), and then transferred via a high-bandwidth bus (e.g., PCIe) to the analyzer's main processing unit for protocol decoding and analysis.
Common Materials
Printed Circuit Board (PCB), FPGA or ASIC, High-Speed Memory (DDR SDRAM), Network PHY Transceiver Chips, Clock Oscillators
Technical Parameters
