ONET8501VRGPRG4

Overview

The ONET8501VRGPRG4 is a laser driver from the Texas Instruments ONET8501V series, designed for differential VCSEL applications. It supports data rates up to 11.3 Gbps and operates on a single supply voltage ranging from 2.95 V to 3.6 V. The device draws a typical operating supply current of 90 mA. It is housed in a QFN-20 package with an exposed pad for thermal management. The component functions as a single-channel driver suitable for high-speed optical interconnects.

Feature Summary

• Supports differential VCSEL driving capabilities
• Operates at data rates up to 11.3 Gbps
• Single-channel architecture for enhanced functionality

Applications

• High-speed optical interconnects
• Data communication systems
• Telecommunications equipment

Procurement Notes

Verify the exact suffix (e.g., VRGPR vs. VRGPRG4) against the manufacturer's official datasheet to ensure pinout and electrical specifications match your design requirements. Confirm RoHS compliance status directly with the supplier or manufacturer documentation, as environmental declarations can vary by production batch and region. Ensure the QFN-20 package footprint aligns with your PCB layout constraints.

Selection Notes

Select this component when a differential output driver is required for VCSEL-based optical links operating at speeds up to 11.3 Gbps. Consider the 90 mA supply current and 2.95 V to 3.6 V operating range during power budgeting. The QFN-20 package requires adequate thermal relief on the PCB due to the exposed pad design. Verify compatibility with the specific VCSEL device being driven regarding current modulation levels.

Part Context

This part belongs to the ONET8501V family of laser drivers manufactured by Texas Instruments. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing variations within the same functional specification. It is distinct from other members of the ONET series that may offer different channel counts or data rate capabilities.

Replacement Considerations

The ONET8501VRGPR is the non-RoHS variant of this component. Verify if the specific RoHS designation is mandatory for your assembly process. No direct cross-brand substitutes are confirmed in public documentation; alternative TI parts must be evaluated for pin-to-pin compatibility and electrical parameter matching.
