• Compact 16-pin TQFN package design suitable for space-constrained layouts

Applications

• High-speed Ethernet network interface cards
• Ethernet switch and router hardware
• Industrial networking equipment requiring robust signal transmission

Procurement Notes

This component is officially classified as obsolete or discontinued by the manufacturer. Verification of availability should focus on secondary market distributors or surplus suppliers rather than direct manufacturing channels. Buyers must confirm the authenticity of stock from non-authorized sources due to the end-of-life status. Design-in alternatives should be evaluated if long-term supply stability is required for production.

Selection Notes

Engineers selecting this component should note its specific 12.5Gbps capability and 3V-3.6V supply requirement. The 16-TQFN package dimensions must be verified against PCB footprint constraints. Since the part is discontinued, replacement strategies should prioritize functional equivalents with compatible pinouts and electrical specifications to ensure seamless integration into existing designs without significant re-validation.

Part Context

The MAX3805 belongs to a family of Ethernet transceivers designed for high-performance networking applications. The ETE suffix indicates the specific temperature grade and packaging variant, while #G16 denotes compliance with environmental directives. As a Maxim Integrated product now under Analog Devices, it represents a legacy solution for Gigabit and 10-Gigabit Ethernet physical layer interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers should consult official Analog Devices resources for current generation replacements that offer backward compatibility or improved performance metrics.
