ONET1101LRGER

Overview

The ONET1101LRGER is a single-channel laser diode driver manufactured by Texas Instruments, designed for high-speed optical interconnects. It supports data rates up to 11.3 Gbps and operates within a supply voltage range of 2.97V to 3.63V. The device is housed in a 24-VQFN (4x4 mm) package with exposed pads for thermal management. Key electrical specifications include a supply current of 95 mA, a modulation current of 85 mA, and a bias current of 100 mA. It functions as a laser diode driver for fiber optic applications and supports surface mount installation.

Feature Summary

• Provides precise control for laser diodes in fiber optic transmission systems
• Supports high-speed serial data transmission at rates up to 11.3 Gbps
• Integrates necessary drive circuitry for direct laser modulation

Applications

• Fiber optic communication links
• High-speed optical transceivers
• Data center interconnects

Procurement Notes

Verify component authenticity through authorized distributors or TI directly. Confirm the specific suffix 'LRGER' matches the required 24-VQFN package and tape-and-reel packaging format. Check for RoHS3 compliance status and ensure the part number corresponds to the active or obsolete lifecycle stage appropriate for your design timeline. Validate that the 2.97V to 3.63V supply requirements align with your system power architecture before procurement.

Selection Notes

Select this component when a single-channel driver is required for direct laser modulation at 11.3 Gbps. Ensure the application utilizes a 2.97V to 3.63V supply rail compatible with the specified current limits. Consider the 24-VQFN footprint constraints and thermal dissipation needs for the 95 mA supply current. This part is suitable for fiber optic interfaces where compact size and high speed are prioritized over multi-channel integration.

Part Context

The ONET1101 series represents Texas Instruments' portfolio of high-speed laser drivers for optical networking. The ONET1101 specifically targets single-channel applications, distinguishing itself from multi-channel transceivers like the ONET1130. It serves as a dedicated driver solution for converting electrical signals into optical pulses for fiber transmission, complementing other family members such as the ONET1141 modulator driver and ONET1151 limiting amplifier.
