MAX3680EAI

Serializers, Deserializers Overview

The MAX3680EAI is a high-performance, low-power optical transceiver module designed for serial data transmission over multimode fiber optic cable. It integrates a laser driver and a limiting photodiode amplifier to support data rates up to 1.25 Gbps. The device operates with a single +3.3V power supply and includes an integrated temperature-compensated bias current control circuit for the laser diode. Key electrical specifications include a -9 dBm average output power, a sensitivity of -19 dBm at 1.25 Gbps, and a supply current of 145 mA typical. The module features automatic power control (APC) and laser protection functions.

Serializers, Deserializers Procurement Notes

Verify the specific suffix EAI against official Analog Devices documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with system voltage requirements and interface standards before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Serializers, Deserializers Selection Notes

Select this component for applications requiring a complete optical transceiver solution with integrated laser control. Consider the 1.25 Gbps data rate and multimode fiber compatibility. Evaluate thermal management needs due to the integrated laser driver. Compare with alternative SFP-compatible transceivers if higher data rates or different fiber types are required.

Serializers, Deserializers Part Context

The MAX3680 series belongs to Maxim Integrated's portfolio of optical transceiver solutions, now part of Analog Devices Inc. These devices are engineered for high-speed serial communication in storage and networking environments. The EAI suffix typically denotes a specific package variant and industrial temperature range, distinguishing it from other commercial or extended temperature options within the same functional family.

Serializers, Deserializers Replacement Considerations

Check for direct pin-to-pin replacements such as the MAX3680EAI+ or other variants within the MAX3680 family that may offer updated packaging or compliance certifications. Verify functional equivalence regarding data rate, power supply, and interface signals before substitution.
