Intelligent laser diode driver (iLDD) targets small form factor (SFF) and small form pluggable (SFP) optical transceiver applications for fibre based data storage and telecom systems.

The single-chip solution integrates the laser diode driver (LDD), the post amplifier (PA) and the diagnostic unit (DU). The digital diagnostic unit intelligently controls the performance of the entire optical module over the full data-rate range from 155 Mbps up to 4.25 Gbps and keeps track of laser safety regulations. Benefits to optical module manufacturers using the single-chip solution include lower cost, decreased power consumption and an improved error-rate. The iLDD chip supports data rates from 155 Mbps up to 4.25 Gbps, offers a high input sensitivity of 4 mV and is capable to drive Vertical Cavity Surface Emitting Laser (VCSEL) as well as edge-emitting laser. The device is fully MSA SFF-8472 compliant, operates from a single supply voltage with extended range from 2.85 V to 3.63 V and has a very low power consumption of 200 mW.
