What are the benefits of LVDS (Low Voltage Differential Signaling) Technology?
High Speed – The transition time of a signal is a limit of how fast you can go. A larger signal swing will take a longer time to transition. One solution to go faster is to decrease the transition time, but that is not practical due to noise, crosstalk, EMI and power reasons. To gain speed, another solution is to lower the swing, resulting in much faster transition times. This can also reduce noise margins, but LVDS solves this problem by using a differential transmission scheme where the signal-to-noise ratio is greatly improved. Low EMI Relatively constant, small output current lowers power/ground noise and since the current in the signal pair is a closely-coupled current loop, fringing electric fields tend to cancel, reducing EMI. Low Power – One of the primary goals of LVDS is LOW POWER dissipation. This has been achieved by using a CMOS process to minimize static current draw. The driver design is current-mode, thus switching spikes are greatly reduced. This lowers EMI, simplifies
