General Description

The MIC3002 is a fiber optic module controller which 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 (4mm x 4mm) QFN package. It also works well as a microcontroller peripheral in transponders or 10Gbps transceivers.
