Abstract
A differential voltage mode driver for implementing symmetric single ended termination includes an output driver circuitry having a predefined termination impedance. The differential voltage mode driver also includes an output driver replica having independently controlled first and second portions. The first and second portions are independently controlled to establish a substantially equal on-resistance of the first and the second portions. The output driver replica controls the predefined termination impedance of the output driver circuitry.
