Lvds 100 ohm termination

WebFor an LVDS output pair, a 100 ohm load between the differential signals is the proper way to terminate the output. The driver, by specification, is current driven and this will create a known balanced state for the drivers. Leaving outputs unterminated may lead to increased noise or jitter on the used outputs. Thank you for your answer. WebI have a generic question about the usage of the off-chip termination (FD_100) with LVDS lines. FD_100 means 100 Ohm Far-end Differential Termination. This is the very common case where you have no termination on the output, but a 100 Ohm across the differential inputs on the receiver side (far-end). Why can you only place this on output lines?
