Microchip's MIC3003 is a fiber optic module controller that enables the implementation of sophisticated, hot-pluggable fiber optic transceivers with intelligent laser control and an internally calibrated Digital Diagnostic Monitoring Interface per SFF-8472. It essentially integrates all non-datapath functions of an SFP transceiver into a tiny (4 mm x 4 mm) MLF® package. It also works well as a microcontroller peripheral in transponders or 10 Gbps transceivers. A highly configurable automatic power control (APC) circuit controls laser bias. Bias and modulation are temperature compensated using dual DACs, an on-chip temperature sensor, and NVRAM look-up tables. A programmable internal feedback resistor provides a wide dynamic range for the APC. Controlled laser turn-on facilitates hot plugging.
