Microchip Technology, Inc. Laser Drivers MIC3003GFL

The MIC3003GFL is a fiber optic module controller designed for sophisticated, hot-pluggable fiber optic transceivers. It is housed in a compact 3mm x 3mm 24-pin MLF package and operates within an extended temperature range of -45¬8C to +105¬8C. This device supports automatic power control (APC) for laser bias, with temperature compensation for modulation and bias parameters using integrated digital sensors and NVRAM look-up tables. The MIC3003GFL features a digital diagnostic monitoring interface compliant with SFF-8472, allowing for the monitoring of critical parameters such as temperature, bias current, and optical power. It includes a programmable internal feedback resistor for dynamic APC range, an analog-to-digital converter for signal monitoring, and a user-writable EEPROM scratchpad for configuration. The device is compatible with a 2-wire SMBus serial interface and can support up to four devices on a single bus. Applications for the MIC3003GFL include SFP/SFP+ optical transceivers, SONET/SDH transceivers, and proprietary optical links, making it suitable for high-speed data communication systems.
