MAX3710ETG+

Overview

The MAX3710ETG+ is a 125Mbps to 2.5Gbps integrated limiting amplifier and burst mode laser driver designed for GPON/EPON ONU applications. It operates on a single 3.3V supply (2.97V to 3.63V) with typical power consumption of 110mA. The device features a low-noise receiver with 1.3mVP-P sensitivity, dual-loop power control (APC and ERC), and a 3-wire digital interface. It supports LVDS, LVPECL, and CML I/Os in a 4mm x 4mm 24-pin TQFN package.

Feature Summary

• Integrates average power control and extinction ratio control loops to eliminate temperature lookup tables.
• Provides a low-noise limiting amplifier with adjustable signal detect thresholds and programmable output levels.
• Includes auto-calibration mode to simplify fiber optic module manufacturing processes.
• Features a 3-wire digital interface for real-time parameter configuration and status monitoring.

Applications

• GPON/EPON Optical Network Unit modules
• BOSA On-Board implementations
• Direct integration on ONU boards

Procurement Notes

Verify the suffix ETG+ corresponds to the standard lead-free RoHS-compliant variant in the TQFN package. Confirm the specific revision level matches the design requirements. Ensure the ordering code aligns with the manufacturer's current production status. Cross-reference the datasheet date code to verify component availability and authenticity through authorized channels.

Selection Notes

Select this component for designs requiring high integration of PMD functions in PON systems. It is suitable for applications needing precise laser power management without external microcontroller complexity. Consider the thermal performance of the exposed pad TQFN package for heat dissipation. Verify compatibility with existing triplexer or ROSA interfaces regarding voltage levels.
