General Description

The MIC3003 is a fiber optic module controller which enables the implementation ofsophisticated, 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) MLF® package. It also works well as a microcontroller peripheral in transponders or 10Gbps transceivers.

Features

• Extended temperature range

•  Alarms and warnings interrupt and TXFAULT masks

•  Capability to support up to four MIC3003 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

   –  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 MLF® package
