Crossbar Switch Matrix

Product Specifications

Technical details and manufacturing context for Crossbar Switch Matrix

Definition

A crossbar switch matrix is a fundamental component within a switch fabric that provides non-blocking connectivity between input and output ports. It consists of a grid of intersecting lines where each intersection contains a switch point that can be independently controlled to establish connections. This architecture enables simultaneous, high-bandwidth data routing in networking equipment, telecommunications systems, and high-performance computing. The matrix is typically implemented on silicon substrates with copper interconnects and dielectric materials for insulation. It supports a configurable matrix size ranging from 8x8 to 64x64 inputs/outputs, with insertion loss of ≤0.5 dB at 1 GHz, isolation of ≥60 dB between channels, and switching time of ≤10 ms from command to stable. Operating frequency spans DC to 18 GHz for broadband performance, with a matched impedance of 50 Ω. Control interfaces include optional Ethernet, RS-232/485. Operating temperature ranges from -40 to 85 °C, with extended range available. Power supply accepts a wide input range of 9–36 V DC. Connector types include SMA, with other types on request. Dimensions are 19" x 10.5" x 1.75" (rack mountable), and weight for a 16x16 unit is ≤5 kg. These specifications serve as directory reference ranges; actual values must be confirmed with the legal manufacturer or supplier for the specific model and application.

Working Principle

The crossbar switch matrix operates by using a grid of horizontal and vertical lines (buses) with switching elements at each intersection. When a connection is required between a specific input and output, the corresponding switch point at their intersection is activated, creating a dedicated pathway. This allows multiple simultaneous connections without interference, as each input-output pair uses a unique path through the matrix. The switching elements are controlled electronically, and the matrix can be reconfigured dynamically to accommodate changing traffic patterns. The design ensures non-blocking operation, meaning any idle input can connect to any idle output without disturbing existing connections. The matrix is typically implemented using semiconductor switches, such as transistors or MEMS, depending on the frequency range and application requirements.
