Abstract:
There is provided a driver circuit including a variable current-source configured to include, a first current-source coupled to a first input node to which a first signal is input from an external, a second current-source coupled to a second input node to which a second signal as an inversion of the first signal is input from the external, a first bypass circuit coupled between the first current-source and the first input node, the first bypass circuit being switched according to the second signal, and a second bypass circuit coupled between the second current-source and the second input node, the second bypass circuit being switched according to the first signal, and a terminal circuit configured to be terminated for an optical device driven by a drive signal according to the first signal, the drive signal being output from an output node coupled between the terminal circuit and the variable current-source.
