General Description
The MIC3000 enables the implementation of sophisticated,
hot-pluggable fiber optic transceivers with intelligent laser
control and 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 inter-
nal feedback resistor provides unprecedented dynamic range
for APC. Controlled laser turn-on facilitates hot-plugging.
An analog-to-digital converter converts the measured tem-
perature, voltage, bias current, transmit power, and received
power from analog-to-digital. Each parameter is compared
against user-programmed warning and alarm thresholds.
Analog comparators and DACs provide high-speed monitor-
ing of received power and critical laser operating parameters.
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 MIC3000 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.
