MAX3286CGI

Laser Drivers Overview

The MAX3286CGI is a high-speed laser driver designed for fiber optic LAN transmitters, optimized for Gigabit Ethernet applications. It operates on a single +3.0V to +5.5V supply voltage and supports data rates of 1.25Gbps and 2.5Gbps. The device features 22ps deterministic jitter and includes an integrated bias generator, laser modulator, and automatic power control (APC) to maintain constant average optical power. It provides 30mA laser modulation current with temperature compensation and offers selectable laser pinning configurations.

Laser Drivers Feature Summary

• Integrates bias generation, laser modulation, and comprehensive safety circuits within a single component.
• Supports Automatic Power Control (APC) to stabilize optical output against temperature variations and laser property changes.
• Features selectable laser pinning options for both common cathode and common anode configurations.

Laser Drivers Applications

• Gigabit Ethernet Optical Transmitter
• Fibre Channel Optical Transmitter
• ATM LAN Optical Transmitter

Laser Drivers Procurement Notes

Verify the specific suffix 'CGI' corresponds to the required package type and temperature range during procurement. Confirm that the component meets all necessary regulatory standards for the intended deployment environment. Ensure compatibility with the target laser diode specifications, particularly regarding modulation current requirements and pinning configuration preferences.

Laser Drivers Selection Notes

Select this component for designs requiring high-speed laser driving in Gigabit Ethernet or Fibre Channel systems. Consider its integrated APC feature for applications demanding stable optical power without external monitoring photodiodes. Evaluate the 22ps deterministic jitter specification against system timing budgets. Ensure the +3.0V to +5.5V supply range aligns with the available power rails in the design.

Laser Drivers Part Context

The MAX3286CGI belongs to the MAX3286/MAX3296 series of high-speed laser drivers from Analog Devices Inc./Maxim Integrated. This series is specifically engineered for shortwave (780nm to 850nm), longwave (1300nm), and VCSEL laser diodes. The CGISuffix typically denotes a specific package variant, such as a QFN or Thin QFN, suitable for surface-mount assembly in compact optical modules.

Laser Drivers Replacement Considerations

The MAX3296 is a related part in the same series offering lower deterministic jitter (7ps). Verify if the jitter performance of the MAX3296 is required for the application. Check for availability of alternative packages within the MAX3286 family if the CGI package is obsolete or unavailable.
