GN7052-CHIP

Overview

The GN7052 is a tri-rate Transimpedance Amplifier (TIA) designed for Passive Optical Network (PON) Optical Line Terminals (OLTs). It supports three data rates: 1.25 Gbps for EPON, 2.5 Gbps for XG-PON, and 10.3 Gbps for 10G EPON. The device provides specific gain settings of 13 kΩ, 1.2 kΩ, and 2.3 kΩ corresponding to the respective rates. Bandwidths are rated at 1.1 GHz, 2.5 GHz, and 8.7 GHz. It operates on a single 3.3V supply.

Feature Summary

• Supports tri-rate operation for multiple PON standards including EPON, XG-PON, and 10G EPON.
• Provides high sensitivity limiting amplification suitable for OLT receiver applications.

Applications

• 1.25G EPON OLT modules
• 2.5G XG-PON OLT modules
• 10G EPON OLT modules

Procurement Notes

Verify the exact ordering suffix against Semtech documentation to confirm package type and temperature range. Confirm that the component matches the specific tri-rate requirement for your PON design. Ensure compatibility with your photodiode interface before procurement.

Selection Notes

Select this TIA when designing OLT receivers requiring support for legacy 1G, 2.5G, and 10G PON standards in a single component. Evaluate the trade-off between the provided gain levels and the required optical input power range for your specific link budget.

Part Context

This component belongs to Semtech's FiberEdge and PON TIA portfolio, which includes devices like the GN7055 and GN7056. These products are engineered for high-performance optical receivers operating within ITU and IEEE transmission systems, specifically targeting PON and FTTH infrastructure.

Replacement Considerations

The GN7055 and GN7056 are listed as limiting TIAs for XGSPON and 10G EPON OLT applications. Verify if these alternatives meet the specific tri-rate requirements or if they are optimized for single-rate implementations.
