App note: Live insertion using low voltage differential signaling


Hot swapping capability of LVDS, app note from Fairchild Semiconductor. Link here (PDF)

Supporting live insertion or hot swapping is important in certain applications such as the ones used in telecommunications systems. These applications require maintenance, upgrades, and repairs to be conducted without shutting down the system or causing disruptions to traffic on the backplane. Inserting and removing cards on a backplane is a capability often required for maximizing system uptime.
This paper will discuss how Low Voltage Differential Signaling (LVDS) technology supports live insertion for multidrop applications and hardware considerations to minimize the effects inserted cards have on a backplane.
