<p>A cable driver is disclosed which provides a substantially linear output signal corresponding to an input signal received by the cable driver on a transmission line. The cable driver includes a number of switches coupled by delay elements which cause the switches to operate in a sequential order in response to an input signal. Each of the switches couples an associated current source to an output port, producing a substantially linear output signal on a transmission line connected to the output port. The substantially linearity of the output signal increases the rate at which data may be transmitted over the transmission line, while permitting the rise and fall time of a specified portion of the output signal to be controlled to ensure that electro-magnetic interference is not produced.</p> |
