WebLVDS termination circuits. Pure differential is the most common configuration, and works well for terminating signals in a well-shielded environment. The center-tapped differential termination splits the 100Ω termination into two 50Ω resistors, with a bypass capacitor at the center tap. This approach works well for noisy environments, as any ... WebThe "proper" termination for an output depends on the type of output (LVPECL/LVDS/CMOS) and the environment in which it is being used. The AD951x data sheets show recommended, or example terminations, for each of the types of outputs. CMOS outputs are generally not terminated - that is, they drive a high impedance input.
