Bus Interface Simulation Model Parameter
The simulated value R_{BDTransmitter} describes the equivalent bus driver output impedance.
R_{BDTransmitter} = 50Ω x ( uBus₁₀₀ – uBus₄₀ ) / ( 2.5 x uBus₄₀ – uBus₁₀₀ )
uBus₁₀₀ =
differential output voltage on a 100Ω||100pF load,
while driving “Data_1” to the bus. Value based on simulation.
uBus₄₀ =
differential output voltage on a 40Ω||100pF load,
while driving “Data_1” to the bus. Value based on simulation.
