ONET1130EPRSMT

Overview

The ONET1130EPRSMT is a laser driver integrated circuit manufactured by Texas Instruments, designed for high-speed optical transceiver applications. It operates within the ONET1130EP series and supports data rates up to 11.7 Gbps. The device is housed in a 32-VQFN package with dimensions of 4x4 mm, suitable for surface mount technology (SMD/SMT). It functions as a limiting amplifier IC specifically tailored for fiber optic networks. The component requires a supply current of 185 mA and dissipates power between 403 mW and 515 mW. It is rated for operation across a temperature range from -40°C to +100°C and carries a moisture sensitivity level of MSL 2.

Feature Summary

• Integrated laser driver architecture optimized for 11.7-Gbps transceiver modules
• Designed specifically for fiber optic network applications
• Compact 32-pin VQFN packaging facilitating surface mount integration

Applications

• Fiber optic network systems
• High-speed optical transceivers
• Laser driver circuits in telecommunication equipment

Procurement Notes

Verify the specific suffix EPRSMT against the official datasheet to confirm the reel packaging quantity of 250 units. Ensure compatibility with the required operating temperature range of -40°C to +100°C for your application environment. Confirm that the 185 mA supply current requirement aligns with your power budget constraints. Check for RoHS compliance status and moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when designing optical links requiring up to 11.7 Gbps data throughput. The 32-VQFN package is appropriate for space-constrained PCB layouts. Consider the 403-515 mW power dissipation profile for thermal management planning. This part is distinct from variants like ONET1130ECRSMT which feature dual CDRs; choose based on whether clock recovery functionality is needed externally or internally.

Part Context

This device belongs to the ONET1130EP family of laser drivers from Texas Instruments. It serves as a specialized amplifier IC for fiber optic networks. The EPRSMT designation indicates a specific tape and reel packaging configuration with a standard factory pack quantity of 250 units. It shares core electrical characteristics with other members of the EP series but differs in packaging and potentially minor operational parameters compared to EC series variants.

Replacement Considerations

ONET1130EPRSMR is a verified substitute offering identical electrical specifications but packaged in reels of 3000 units instead of 250.
