Figure VC1013 Block Diagram
Termination resistors provided serial input, well serial output. Input termination resistors common these speeds, internal output termination deserves special mention. absorbs reflections from impedance discontinuities, increasing available signal margin. value each internal termination resistors closely matched that single external resistor placed across RREF+ RREF- pins.
