Abstract:
A circuit configuration for performing directly electrically isolated broadband transmission, comprising:an input stage including at least one first logic signal combination device, a first line for transmitting a clock signal, a second line for transmitting a data signal, and a connection to a first ground potential; an output stage including at least one second logic signal combination device, a filter connected downstream of said second logic signal combination device, and a connection to a second ground potential; and a decoupling device; said first logic signal combination device having a first signal input receiving the data signal, and a second signal input receiving the clock signal; said first logic signal combination device including a first signal output outputting a first output signal to said decoupling device, the first output signal consisting of the data signal superposed on the clock signal; said decoupling device decoupling said input stage from said output stage by generating a decoupled clock signal from the clock signal and by generating a decoupled first output signal from the first output signal; said second logic signal combination device including a third signal input receiving the decoupled first output signal from said decoupling device; said second logic signal combination device including a fourth signal input receiving the decoupled clock signal from said decoupling device; said second logic signal combination device including a second signal output outputting a second output signal consisting of decoupled data signal that is separated from the decoupled clock signal; said second signal output always outputting defined signals; said filter configured for filtering out interference pulses contained in the second output signal to generate a third output signal that is a filtered decoupled data signal; and said decoupling device decoupling said input stage from said output stage such that the first ground potential is directly electrically isolated from the second ground potential and such that the clock signal and the first output signal are transmitted in a directly electrically isolated manner from said input stage to said output stage.
