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
