FOM Management IC with Internal

Calibration

Consider MIC3003 for New Designs

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-data path functions of an SFP transceiver into a

tiny (4mm

4mm) QFN package.

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.

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.

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.
