Abstract
A line driver () for transmitting data with high bit rates, in particular for wire-bound data transmission in the full-duplex process, comprises a differential pair with differential pair transistors () for generating transmission impulses as a function of the data to be transmitted, whereby the transmission impulses are preferably output via cascode transistors (), each with the differential pair transistors () forming a cascode circuit, onto the data transmission line () connected to the line driver (). For reproducing the behaviour of the differential pair a replica differential pair with replica differential pair transistors () is provided, generating replica impulses corresponding to the transmission impulses, which replica impulses can be fed via replica cascode transistors () to a hybrid integrated circuit () for effecting echo compensation in relation to impulses received via the data transmission line ()
