DS3902 is a response to market requirements for low cost solutions in Optical Modules which do not have stringent requirements for accurate temperature tracking of some laser characteristics; such as modulation current and extinction ratio. In addition, laser drivers having two closed loop control need a way of setting APC and modulation currents set points. Conventionally this has been done using mechanical potentiometers first, then these mechanical Pots are replaced with fixed resistors selected to have equal values.
