Product Specifications

Technical details and manufacturing context for Crossbar Switch

Definition
A crossbar switch is a fundamental component within an interconnect router that enables simultaneous, non-blocking connections between multiple input and output ports. It functions as a matrix switch where any input can be connected to any output without interfering with other connections, facilitating high-speed data routing and switching in networking and computing systems.
Working Principle
The crossbar switch operates using a matrix of switching elements at each intersection of input and output lines. When a connection is required between a specific input and output, the corresponding switching element at that intersection is activated, creating a dedicated path. This allows multiple connections to occur simultaneously without contention, as each input-output pair has its own independent switching point.
