MAX3660ETE+

Overview

The MAX3660ETE+ is a high-linearity analog RF transimpedance amplifier (TIA) designed for passive optical network video receiver applications. It features a maximum variable gain of 66dBΩ and integrated uptilt, providing 23dBmV/channel output at 870MHz. The device supports extended frequency operation beyond 1000MHz with a single +5V supply. Key electrical parameters include an equivalent input noise of 4.5pA/Hz^1/2 without a photodiode, an OIP2 of 58dBm, and an OIP3 of 24dBm. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin TQFN-EP package.

Feature Summary

• Pin-compatible with the MAX3654 for simplified design transitions
• Operates effectively at frequencies exceeding 1000MHz
• Requires no input matching network due to very low true-TIA input impedance
• Consumes 650mW dissipation while operating on a single +5V supply

Applications

• FTTH Optical Network Termination (ONT)
• Passive Optical Network (PON) video receivers
• Analog CATV signal processing

Procurement Notes

Verify that the specific ordering suffix matches the required thermal and environmental specifications. Confirm the package type corresponds to the 16-pin TQFN-EP configuration. Ensure compatibility with existing board layouts by checking pin assignments against reference designs. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when designing PON video receivers requiring high linearity and wide dynamic range. The integrated uptilt simplifies circuit architecture by eliminating external passive tilt networks. Consider the feed-forward AGC capability for maintaining consistent output levels across varying optical input conditions.

Part Context

This device belongs to the Maxim Integrated family of analog RF transimpedance amplifiers. It is specifically engineered for fiber optic communication systems where high signal fidelity is critical. The exposed pad design facilitates efficient heat dissipation and robust electrical grounding for high-frequency performance.

Replacement Considerations

The MAX3654 is documented as pin-compatible with the MAX3660ETE+. Verify functional requirements and electrical characteristics before substituting.
