ONET1191VRGPR

Overview

The ONET1191VRGPR is a single-channel laser driver IC designed for optical networking applications. It supports data rates up to 11.3 Gbps and operates within a supply voltage range of 2.9V to 3.6V. The device features a modulation current of 45mA and a bias current of 20mA, with a total supply current of 70mA. It is housed in a 20-VQFN package (4x4 mm) with exposed pads, suitable for surface-mount installation. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Single-channel architecture optimized for fiber optic transmission systems
• Integrated control circuitry supporting high-speed serial data modulation
• Compact 20-pin QFN footprint facilitating dense board layouts

Applications

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

Procurement Notes

Verify the specific suffix 'VRGPT' against the datasheet to confirm pinout and thermal pad configuration. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices or product change notifications from Texas Instruments. Ensure ESD handling protocols are followed during storage and placement. Validate that the 20-QFN package matches the target PCB footprint dimensions.

Selection Notes

Select this component when a single-channel driver is required for 11.3 Gbps optical links. Consider the 2.9V to 3.6V supply range compatibility with system power rails. Evaluate the 20-QFN package size against available board space constraints. Compare thermal performance requirements against the exposed pad design. Verify interface compatibility with upstream serializer/deserializer circuits.
