ONET1191PRGTT

Overview

The ONET1191PRGTT is a laser driver component from Texas Instruments, classified as a limiting amplifier within the ONET1151P series. It operates at a data rate of 11.3 Gb/s and functions as a differential VCSEL driver. The device utilizes a VQFN-16 package with surface mount installation. It supports a supply voltage range from 2.9 V to 3.6 V and draws a typical operating supply current of 52 mA. The operational temperature range spans from -40°C to +100°C.

Feature Summary

• Functions as a high-speed limiting amplifier for optical signal processing
• Designed specifically for differential VCSEL driver applications
• Supports operation in extended industrial temperature environments

Applications

• Fiber optic networking systems
• Optical interconnect modules
• High-speed data transmission links

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Cross-reference datasheet revisions to ensure compatibility with existing design specifications. Validate that the specific suffix matches required performance criteria before integration into production workflows.

Selection Notes

Select this component for designs requiring a dedicated limiting amplifier with integrated VCSEL drive capability. Ensure the system power budget accommodates the specified 52 mA supply current. Verify that the PCB layout supports the VQFN-16 footprint and thermal requirements for operation up to 100°C. Consider availability constraints given the product lifecycle status when planning long-term manufacturing.

Part Context

This part belongs to the ONET1151P series of laser drivers manufactured by Texas Instruments. It serves as a specialized integrated circuit for optical communication interfaces. The component is distinct from general-purpose amplifiers due to its optimized characteristics for driving vertical-cavity surface-emitting lasers in high-speed data links.

Replacement Considerations

Public records indicate the ONET1191PRGTR is a related variant within the same family. Verify pinout and electrical parameter compatibility before substitution. No other direct substitute part numbers are confirmed in available documentation.
