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.

特性 Features

• Extensive temperature range

• Alarms and Warnings interrupt and TXFAULT masks

• Capability to support up to four chips on the serial interface

• LUT to compensate for chip-FOM case temperature difference

• 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, and fault levels via NVRAM look-up tables

• NVRAM to support GBIC/SFP serial ID function

• User writable EEPROM scratchpad

• 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

– Internal or external calibration

– EEPOT for adjusting RX power measurement

• Power-on hour meter
