MIC3002

FOM Management IC with Internal

Calibration

General Description

Features

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

• 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

also works well as

microcontroller peripheral in

• APC or constant-current laser bias

transponders or 10Gbps transceivers.

• 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

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 a wide dynamic range for

the 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.

• 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

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.

• 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

In addition to the features listed above which are already

implemented in the previous controller MIC3001, the

MIC3002 features an extensive temperature range, options

to mask alarms and warnings interrupt and TXFAULT, and

ability to support up to four chips with the same address on

the serial interface.

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

Communication with the MIC3002 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

• SFP/SFP+ optical transceivers

• SONET/SDH transceivers and transponders

• Fibre Channel transceivers

• 10Gbps transceivers

• Free space optical communications

• Proprietary optical links
