• Supports high-speed serial data transmission up to 4.25 Gbps
• Integrated active back termination for signal integrity
• Operates on a single low-voltage power supply

Applications

• Optical line cards
• Point-to-point microwave backhauls
• Video over fiber systems

Procurement Notes

Verify the specific suffix 'GET' against the manufacturer's official datasheet to confirm pinout and packaging details. Confirm end-of-life status with the supplier prior to procurement, as discontinuance notifications may affect long-term availability. Ensure compatibility with existing thermal management solutions for the VQFN-24 package.

Selection Notes

Select this component for designs requiring a compact laser driver solution supporting OC-192/STM-64 speeds. Evaluate the 45 mA supply current against system power budgets. Consider the VQFN-24 footprint constraints during PCB layout. Verify that the 3 V to 3.6 V supply range aligns with the target board voltage rails.

Part Context

This part belongs to the ONET4211LD series of laser drivers from Texas Instruments. It is engineered for high-performance optical interconnects. The device integrates necessary drive circuitry into a small form factor, simplifying design complexity for transceivers and modules requiring reliable high-speed optical signal generation.

Replacement Considerations

Consult the manufacturer's obsolescence notification for officially confirmed substitute part numbers. Cross-reference electrical specifications and pinouts before considering alternative components.
