Claim:
1. A system comprising a data transmission circuit for transmitting a data signal over a transmission line, wherein the data transmission circuit comprises: a digital to analog converter (DAC) configured to receive N-bit input digital values of the data signal, generate therefrom 2 a multiplexer configured to receive a plurality of N-bit input digital values in parallel and time multiplex the plurality of N- bit input digital values for provision serially to the DAC, wherein the multiplexer receives two groups of N-bit input digital values in parallel and time multiplexes one of the two groups of N-bit input digital values on a rising edge of a clock signal and time multiplexes another of the two groups of N-bit input digital values on a falling edge of said clock signal, and N>1.
