ONET1151PRGTR

Overview

The ONET1151PRGTR is a laser driver manufactured by Texas Instruments, belonging to the ONET1151P series. It functions as an 11.3 Gbps limiting amplifier designed for optical transmission applications. The device operates on a single +3.3V power supply with a typical operating supply current of 52 mA. It is housed in a VQFN-16 package and supports surface mount installation. The component is rated for operation within an ambient temperature range of -40°C to +100°C.

Feature Summary

• Functions as a high-speed limiting amplifier for direct modulation of lasers at data rates up to 11.3 Gbps.
• Operates efficiently from a single +3.3V power supply source.
• Utilizes a compact VQFN-16 package suitable for space-constrained surface mount designs.

Applications

• Optical transmitter modules
• High-speed fiber optic communication links

Procurement Notes

Verify the specific suffix 'PRGTR' against official documentation to confirm package type and reel specifications. Confirm end-of-life status, as this part number may be discontinued or subject to limited availability. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this component when a dedicated limiting amplifier stage is required rather than a full integrated laser driver with bias control. Verify that the system design provides external biasing and automatic power control loops, as this model focuses primarily on signal amplification. Check if the VQFN-16 footprint aligns with board layout constraints compared to other variants in the family.

Part Context

This device is part of the ONET1151P product line from Texas Instruments. It serves as a specialized amplifier solution distinct from complete laser drivers like the ONET1151L, which include integrated bias and APC circuits. The PRGTR designation indicates a specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer obsolescence notices for potential alternative components within the same product family.
