MIC3003
FOM Management IC
with Internal Calibration
General Description
Features
The MIC3003 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)
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 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 fast
monitoring of received power and critical laser operating

Extended temperature range
Alarms and warnings interrupt and TXFAULT masks
Capability to support up to four MIC3003 on one SMBus
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
Integrated digital temperature sensor
Temperature compensation of modulation, bias, bias fault
and alarm thresholds via NVRAM look-up tables
NVRAM to support GBIC/SFP serial ID function
User writable EEPROM scratchpad
Reset signal compatible with some new systems
requirements
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
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 which are already
implemented in the previous MIC300x controllers, 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.
