MIC3001GMLTR

IC FOM MANAGEMENT W/CALIBR 24MLF

General Description

The MIC3001 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 MLF® package. It also works well as a microcontroller peripheral in transponders or 10Gbps transceivers.

Features

• 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

• Drives external low-cost BJT for laser bias

• Integrated digital temperature sensor

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

• Direct interface to SY88932, SY88982, SY89307 and other drivers

• 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,

   – 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 I2C compatible serial interface

• SFP MSA and SFF-8472 compliant

• 3.0V to 3.6V power supply range

• 5V-tolerant I/O

• 4mm x 4mm 24-pin MLF® package

Applications

• SFF/SFP optical transceivers

• SONET/SDH transceivers and transponders
