MIC3003GFL
FOM Management IC
with Internal Calibration General Description Features 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)
MLFВ® 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 …
