Differential termination network for differential transmitters and receivers

摘要: A system of terminating a differential transmission line is described, where the transmitter and receiver are supplied by different power sources. The termination circuit comprises an unbalanced voltage divider pair, connection to receiver's source, adjustable threshold voltage, circuitry reduce consumption. An pair provides matched impedances, prevents undesired output upon loss signals. supplying at inputs source. minimum input on which signals can be superimposed. Power consumption reduced through use current limiter, coupled with high pass filter maintain characteristic impedance during frequency transmission. SEP
