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.

Features

? Extensive temperature range

? Alarms and Warnings interrupt and TXFAULT masks

? Capability to support up to four chips on the serial interface

? LUT to compensate for chip-FOM case temperature difference

? 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, and fault levels via NVRAM look-up tables

? NVRAM to support GBIC/SFP serial ID function

? User writable EEPROM scratchpad

? Diagnostic monitoring interface per SFF-8472

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

– S/W control and monitoring of TXFAULT, RXLOS, RATESELECT, and TXDISABLE

– Internal or external calibration

– EEPOT for adjusting RX power measurement

? Power-on hour meter

? Interrupt capability

? Extensive test and calibration features

? 2-wire SMBus-compatible serial interface

? SFP/SFP+ MSA and SFF-8472 compliant

? 3.0V to 3.6V power supply range

? 5V-tolerant I/O

? Available in (4mm x 4mm) 24-pin QFN package

Applications

? SFP/SFP+ optical transceivers

? SONET/SDH transceivers and transponders
