MIC3002
FOM Management IC with Internal
Calibration
General Description
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
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 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.
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.
Communication with the MIC3002 is via an industry standard
2-wire serial interface. Nonvolatile memory is provided for
