MAX3660ETE+T

Overview

The MAX3660ETE+T 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, delivering 23dBmV/channel at 870MHz with feed-forward automatic gain control. The device supports extended frequency operation beyond 1000MHz and operates on a single +5V supply. Key electrical parameters include an output second-order intercept point (OIP2) of 58dBm, an output third-order intercept point (OIP3) of 24dBm, and a typical equivalent input noise of 4.5pA/Hz^1/2 without a photodiode. It functions within a temperature range of -40°C to +85°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm the presence of the lead-free/RoHS-compliant suffix (+) in the ordering information. Ensure the TQFN-EP package condition meets thermal requirements, as the exposed pad must be soldered to ground for proper performance. Cross-reference datasheet revisions to ensure compatibility with current design specifications.

Selection Notes

Select this component for designs requiring high linearity and wide dynamic range in PON video receivers. The integrated uptilt simplifies circuit topology by eliminating external passive tilt networks. Consider the pin compatibility with the MAX3654 if migrating from previous generations. Ensure the application utilizes a single +5V supply and accommodates the specific thermal management needs of the TQFN-EP package.

Part Context

The MAX3660ETE+T belongs to the MAX3660 series of analog CATV transimpedance amplifiers manufactured by Analog Devices Inc./Maxim Integrated. It is specifically engineered for high-performance optical receiver front-ends in fiber-to-the-home networks. The device integrates critical signal conditioning functions into a compact 16-pin TQFN-EP package, optimizing space and performance for modern telecommunication infrastructure.

Replacement Considerations

The MAX3660 is pin-compatible with the MAX3654. Verify that the replacement part number matches the specific suffix requirements for temperature range and packaging configuration.
