MIC3001

FOM Management IC with Internal

Calibration

Consider MIC3002 for New Designs

General Description

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

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.

A highly configurable automatic power control (APC)

circuit controls laser bias. Bias and modulation are

temperature compensated using dual DACs, an on-chip

temperature sensor, and NVRAM look-up tables. A

programmable internal feedback resistor provides

unprecedented dynamic range for APC. Controlled laser

turn-on facilitates hot plugging.

An analog-to-digital converter converts the measured

temperature, voltage, bias current, transmit power, and

received power from analog to digital. An EEPOT

provides front-end adjustment of RX power. Each

parameter is compared against user-programmed

warning and alarm thresholds. Analog comparators and

DACs provide high-speed monitoring of received power

and critical laser operating parameters. Data can be

reported as either internally calibrated or externally

calibrated.

– 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

An interrupt output, power-on hour meter, and data-

ready bits add user friendliness beyond SFF-8472. The

interrupt output and data-ready bits reduce overhead in

the host system. The power-on hour meter logs

operating hours using an internal real-time clock and

stores the result in NVRAM.

• 4mm x 4mm 24-pin MLF^®package

Communication with the MIC3001 is via an industry

standard 2-wire serial interface. Nonvolatile memory is

provided for serial ID, configuration, and separate OEM

and user scratchpad spaces. Two-level password

protection guards against data corruption.

Applications

• SFF/SFP optical transceivers

• SONET/SDH transceivers and transponders

• Fibre channel transceivers

• 10Gbps transceivers

• Free space optical communications

• Proprietary optical links
