Abstract
A communication device includes a controller, a differential input termination resistor, a linear laser driver, transmitted signal detector, a linear transimpedance amplifier, a linear variable gain amplifier, a linear output driver, a pulse counter, a received signal detector, and an amplitude detector. The controller outputs a Term signal for setting a resistance value of the differential input termination resistor, a TxEN signal and an LS signal for controlling an operation of the linear laser driver, an RxEN signal for controlling operations of the linear TIA, the linear VGA, and the linear output driver, and a GCTL signal for controlling a gain of the linear VGA.
