Low-Voltage Differential Signaling (LVDS) Application Note 1382-6 by Stephen Kempainen, National Semiconductor Who Should Read This Application Note? Digital designers utilizing lowvoltage differential signaling (LVDS) for high-speed data transmissiom. LVDS Provides Higher Bit Rates, Lower Power, and Improved Noise Performance Due to the Internet’s tremendous growth, data transfers are increasing dramatically in all areas of munications. In addition, data streams for digital video, HDTV, and color graphics are requiring higher and higher bandwidth. The digital munications deluge is the driving force for high-speed interconnects between chips, functional boards, and systems. The data may be digital, but it is analog Low Voltage Differential Signaling (LVDS) that designers are choosing to drive these high-speed transmission lines. LVDS’s proven speed, low power, noise control, and cost advantages are popular in point-to-point applications for telemunications, data munications, and displays. LVDS uses high-speed analog circuit techniques to provide multi-gigabit data transfers on copper interconnects. Wherever you need high-speed data transfer (100 Mb/s and higher), LVDS offers a solution. There are many applications in many market segments that use LVDS for data transmission. These include: - stackable hubs for data munications - wireless base stations and ATM switches in telemunications - flat-panel displays and servers in the puter market - peripherals like printers and digital copy machines - high-resolution displays in industrial applications - flat-panel displays in the automotive market In these applications, high-speed data moves within and between systems. Moving data within a system (intrasystem data transfer) is the main use for LVDS solutions today. Moving information between systems (intersystem data transfer) requires standard munication protocols such as IEEE 1394, Fibre Channel, and Gigabit Ethernet. Since the hardware and software overhead for...
