MAX3632ETG+T

Overview

The MAX3632ETG+T is a burst-mode limiting amplifier designed for GPON OLT receiver applications at 622Mbps and 1244Mbps. It operates from a single +3.3V supply over a -40°C to +85°C temperature range. The device provides an electrical input sensitivity of 4mVP-P, supporting GPON class-B optical sensitivity with a PIN photodiode. It features LVPECL-compatible data outputs and reset inputs (RST) to control the offset correction loop for burst-mode operation.

Feature Summary

• DC-coupled limiting amplifier architecture optimized for burst-mode GPON applications
• Operates in conjunction with Maxim’s burst-mode transimpedance amplifiers (MAX3630/MAX3631)
• Provides LVPECL data output signals
• Includes LVPECL-compatible reset (RST) and hold (HOLD) inputs for offset correction control

Applications

• 622Mbps GPON OLT Receivers
• 1244Mbps GPON OLT Receivers

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status via official documentation. Ensure the package matches the specified 24-lead thin QFN form factor. Validate that the ordering suffix corresponds to the correct temperature range and packaging configuration before finalizing procurement.

Selection Notes

Select this component when designing GPON OLT receivers requiring burst-mode signal processing at 622Mbps or 1244Mbps. It must be paired with compatible burst-mode TIAs like the MAX3630 or MAX3631. Ensure the design supports LVPECL termination requirements and accommodates the specific timing constraints for the RST and HOLD inputs during burst transitions.

Part Context

This part belongs to the MAX3632 series of burst-mode limiting amplifiers manufactured by Analog Devices / Maxim Integrated. It is specifically engineered for optical line terminal (OLT) applications within Gigabit Passive Optical Network (GPON) systems, functioning as the post-amplification stage following the transimpedance amplifier.
