Modular routers generally are deployed in the core of a service providers network and enterprise backbones. They consist of slots that contain redundant switch cards, line cards, a high-speed backplane, and power supply modules. As the IP, voice, and data traffic volume continues to grow exponentially at the core of the network, the modular routers are evolving by upgrading the speed of the backplane, increasing the port densities, and adding more testability. National Semiconductor has leveraged its high-speed analog expertise to meet these trends by providing industry-leading solutions for backplane data transfer, port side connectivity, power management, and testability.
Component Highlights
*High Voltage Power Systems - provide both in-rush current control and short-circuit protection for hot swap enabled devices.
*Backplane Control Interface - networking solutions with speeds up to 1000 Mbit/s.
*Backplane Data Transfer Interface - offers 40 Gbps total full duplex throughput along with less then 10-15 bit-error rate.
*JTAG Mux and JTAG Master Block - functions as a test master for a IEEE 1149.1 test system using 16-bit data interface.
*Base Board Management - offers autonomous system reset, integrated ADC channels, and fan control.
