National Semiconductor has announced a family of automotive-grade low-voltage differential signalling (LVDS) 2 x 2 crosspoint switches that deliver the industry’s best signal integrity and noise immunity at data transmission rates up to 3.125 Gbps. These PowerWise crosspoints, which consume as little as 105 mW of power per channel, combine with National’s line drivers and receivers to reduce power consumption and heat dissipation in a wide range of automotive applications including infotainment, instrument cluster displays, GPS navigation, and backup and lane departure camera warning systems.

National’s LVDS family has been characterized and qualified to meet the certification requirements of the AEC-Q100 standard as defined by the Automotive Electronics Council. LVDS is a robust differential signaling technology that’s well-suited for automotive applications. It provides low power operation and high bandwidth, yet generates very little electromagnetic interference (EMI). Additionally, the wide LVDS common-mode and differential technology deliver exceptional noise immunity. This combination of low noise (EMI) generation and high noise immunity is critical as electronic systems continue to proliferate throughout the automobile in areas such as ignition, power-train management, infotainment and safety.

The eight new LVDS devices include three 2 x 2 crosspoint switches, a set of single and dual differential drivers and receivers, and a dual line driver and receiver pair. Each device is AEC-Q100 Grade 3 certified and guaranteed to operate up to 85 degrees C.
