MIC3001GML

General Description

The MIC3001 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.

Features

• 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
• Drives external low-cost BJT for laser bias
• Integrated digital temperature sensor
• Temperature compensation of modulation, bias, and fault levels via NVRAM look-up tables
• Direct interface to SY88932, SY88982, SY89307 and other drivers
• 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,
– 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
• Interrupt capability
• Extensive test and calibration features
• 2-wire I2C compatible serial interface
• SFP MSA and SFF-8472 compliant
• 3.0V to 3.6V power supply range
• 5V-tolerant I/O
• 4mm x 4mm 24-pin MLF® package
