MIC3000

FOM Management IC

General Description

Features

The MIC3000 enables the implementation of sophisticated,

hot-pluggable fiber optic transceivers with intelligent laser

control and Digital Diagnostic Monitoring Interface per SFF-

8472. It essentially integrates all non-datapath functions of an

SFPtransceiverintoatiny4mmx4mmMLF package. Italso

works well as a microcontroller peripheral in transponders or

10Gbps transceivers.

• APC or constant-current laser bias

• 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,

and supply voltage

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 inter-

nalfeedbackresistorprovidesunprecedenteddynamicrange

for APC. Controlled laser turn-on facilitates hot-plugging.

An analog-to-digital converter converts the measured tem-

perature, voltage, bias current, transmit power, and received

power from analog-to-digital. Each parameter is compared

against user-programmed warning and alarm thresholds.

Analog comparators and DACs provide high-speed monitor-

ing of received power and critical laser operating parameters.

– S/W control and monitoring of TXFAULT, RXLOS,

RATESELECT, and TXDISABLE

– External calibration

• Power-on hour meter

• Interrupt capability

• Extensive test and calibration features

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.

• 2-wire I C 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

Communication with the MIC3000 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
