Abstract

Embodiments herein describe an ASIC design where certain portions of the laser driver are controllable by the user. In one embodiment, the ASIC may include one or more pins which provide a connection interface where the user can electrically connect a sense resistor that corresponds to the particular laser being used. The remaining portions of the laser driver are implemented in the ASIC, thereby giving the user the flexibility to adapt the laser driver to her selected laser while having the advantages that come from using an ASIC.
