ONET1191PRGTR

Overview

The ONET1191PRGTR is a limiting amplifier IC designed for optical networking applications. It operates at data rates up to 11.3 Gb/s and functions within a supply voltage range of 2.9 V to 3.6 V. The device draws a typical operating supply current of 72 mA. It is housed in a compact 16-VQFN package with dimensions of 3x3 mm, featuring exposed pad technology for thermal management. The component supports surface mount installation and is available in reel, cut tape, and Digi-Reel packaging formats.

Feature Summary

• Provides high-speed signal amplification for optical fiber networks
• Supports differential input and output configurations
• Designed for low power consumption in dense circuit layouts

Applications

• Optical fiber network systems
• High-speed data transmission interfaces
• Telecommunications equipment

Procurement Notes

Verify the specific suffix 'RGTR' to confirm the reel-based packaging variant. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the 16-VQFN footprint matches the target PCB design constraints before integration.

Selection Notes

Select this component when a dedicated limiting amplifier is required for 11.3 Gb/s optical links. Consider the 16-VQFN package size for space-constrained designs. Evaluate the 72 mA supply current against system power budgets. Verify compatibility with existing laser driver or transimpedance amplifier stages in the optical path.

Part Context

This part belongs to the ONET1191 family of optical interconnect components from Texas Instruments. It serves as a specialized amplifier stage distinct from general-purpose operational amplifiers like the OPA191 series. The device is engineered specifically for the demanding bandwidth and linearity requirements of modern optical communication infrastructure.
