General Description

The MIC3003GFL 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-data path functions of an SFP/SFP+ transceiver into a tiny (3mm x 3mm) MLF® package. It also works well as a microcontroller peripheral in transponders or 10Gbps transceivers. The MIC3003GFL uses the same die as the MIC3003 with all its functions, but in a smaller package and different pin out.

Features

• Packaged in a ultra small (3mm x 3mm) 24-pin MLF® package

• Extended temperature range

• Alarms and warnings interrupt and TXFAULT masks

• Capability to support up to four devices on one SMBus

• APC or constant-current laser bias

• Turbo mode for APC loop start-up and shorter laser turn on time

• Supports multiple laser types and bias circuit topologies

• Integrated digital temperature sensor

•Temperature compensation of modulation, bias, bias fault and alarm thresholds via NVRAM look-up tables

• NVRAM to support GBIC/SFP serial ID function

• User writable EEPROM scratchpad

• Reset signal compatible with some new systems requirements

• Diagnostic monitoring interface per SFF-8472

 –  Monitors and reports critical parameters: temperature, bias current, TX and RX optical power, and supply voltage
