National LVDS chips comply with AEC-Q100 automotive standard

Santa Clara, Calif.—National Semiconductor Corp. announced a family of automotive-grade low-voltage differential signaling (LVDS) 2 x 2 crosspoint switches that deliver high signal integrity and noise immunity at data transmission rates up to 3.125 Gbit/s.

These PowerWise crosspoints, which consume 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.

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°C.

The PowerWise DS25CP102Q 2 x 2 LVDS crosspoint switch delivers jitter performance (6 ps typical) at data transmission rates up to 3.125-Gbit/s. The device features selectable transmit pre-emphasis and receive equalization to extend signal transmission reach in cables and FR-4 backplanes. It's supplied in a 16-pin LLP package.
