Abstract
A digital controller for a laser driver has a register for storing control data that serve to control an analog circuit of the laser driver. A first interface receives operating data from a local memory. A second interface receives external user data. A control unit controls the data communication between the first and second interfaces and the register. The digital controller thus takes over the trimming process and other communication and control functions of the laser driver. The required information for this is contained in the operating and/or user data.
