MIC3003GFL

FOM Management IC

with Internal Calibration

General Description

The MIC3003GFL 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-data path

functions of an SFP/SFP+ transceiver into a tiny (

3mm x 3mm

)

MLF

package. It also works well as a microcontroller

peripheral in transponders or 10Gbps transceivers. The

MIC3003GFL uses the same die as the MIC3003 with all its

functions, but in a smaller package and different pin out.

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.

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 fast

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.

In addition to the features listed above, the MIC3003

features an extended temperature range, options to mask

alarms and warnings interrupt and TXFAULT, a reset signal

source, and the ability to support up to four chips with the

same address on the serial interface. It also supports eight-

byte SMBus block writes.

Communication with the MIC3003 is via an industry

standard 2-wire SMBus serial interface. Nonvolatile

memory is provided for serial ID, configuration, and

separate OEM and user scratchpad spaces.
