Welcome to the first installment of our Everyday App Note Series! Today\u2019s application note comes from Texas Instruments, one of the leading experts on high-speed design. They\u2019ve dug deep to uncover solutions for timing errors during high-speed Analog-to-Digital Conversion (ADC) when using Low Voltage Differential Signaling (LVDS) and a Field Programmable Gate Array (FPGA). <\/span><\/p>\n\n\n\n

Who Is This App Note For?<\/h2>\n\n\n

The LVDS standard does not define any connectors and protocols, which makes it easily adaptable into a variety of high-speed applications. This app note is perfect for any designer troubleshooting timing errors during high-speed analog-to-digital conversion with an LVDS data interface and an FPGA. <\/span><\/p>\n\n\n

Why Should You Read This App Note?<\/h2>\n\n\n

LVDS is one of the most popular differential signaling standards for electronics design and offers an ideal interface between an ADC and FPGA. If you\u2019re battling timing errors using single-ended signaling schemes like Complementary Metal-Oxide-Semiconductor (CMOS), then this app note is worth your time.<\/span><\/p>\n\n\n\n

It\u2019s a well-known fact that differential signaling with LVDS greatly reduces noise on high-speed layouts than single-ended schemes like CMOS. By using two wires with opposite current and voltage swings in a differential signal, you get several benefits, including:<\/span><\/p>\n\n\n\n
