Abstract
A transmission line driver circuit for use in data communication transmitters that is capable of meeting the return loss specifications as well as the electrical interface specifications as defined by C.C.I.T.T. standards for E1/T1 transmission. The line driver circuit of the present invention maintains minimum output impedance during the entire dynamic range of the transmit signal while meeting the pulse shape template requirements. The circuit includes a predriver stage that controls the slew rate of the transmit signal within the constraints of the pulse template. This allows a subsequent output driver stage to enjoy fast slew rates, large gain and dynamic range, and very small output impedance to meet the return loss specification.
