Patent ID: 8461868

Claim:
A chip comprising a signal transmitting circuit, said signal transmitting circuit further comprising: a multi-route selector, comprising a first input end, a second input end, a selection input end and an output end; wherein said first input end of said multi-route selector is grounded, said second input end is connected to a DC bias voltage and said selection input end receives a selection signal; a first bias resistor and a second bias resistor, one end of each of said first bias resistor and second bias resistor being connected to said output end of said multi-route selector respectively; a first signal line and a second signal line, coupling to the other end of said first bias resistor and the other end of said second bias resistor respectively; a signal transmitting end, transmitting a pair of differential signals through said first signal line and said second signal line; wherein said multi-route selector selects said first input end when said selection signal is a first selection signal, and said multi-route selector selects said second input end when said selection signal is a second selection signal.
