ONET1151MRGTR

Overview

The ONET1151MRGTR is a high-speed, 3.3-V differential modulator driver designed for data rates up to 11.35 Gbps. It features output waveform shaping and a 2-wire serial interface for digital control of equalization, pre-emphasis, and eye crossing point. The device operates within a temperature range of -40°C to +100°C and is housed in a VQFN-16 package.

Feature Summary

• Differential modulation driver with integrated output waveform shaping capabilities
• Digital control via 2-wire serial interface for parameter adjustment
• High-speed operation supporting data rates up to 11.35 Gbps

Applications

• Modulating differentially driven Mach Zehnder Modulators
• High-speed optical communication systems
• Data center interconnects requiring precise signal integrity

Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific suffix 'RGTR' matches the required reel packaging and tape specifications. Ensure the part number corresponds to the discontinued status if sourcing from secondary markets, as availability may be limited. Cross-reference the datasheet revision to ensure compatibility with current design requirements.

Selection Notes

Select this component when designing systems that require a dedicated differential driver for Mach Zehnder modulators at speeds exceeding 10 Gbps. The integrated waveform shaping reduces external component count. Consider the VQFN-16 package size for space-constrained PCB layouts. Verify thermal performance within the specified -40°C to +100°C operating range for the intended application environment.

Part Context

The ONET1151M series represents Texas Instruments' solution for high-bandwidth optical modulation. This specific model integrates driver amplification and shaping into a single compact package. It belongs to the ONET family of laser drivers, optimized for coherent and direct detection optical transceivers. The MRGTR variant denotes the surface-mount reel packaging configuration.

Replacement Considerations

Texas Instruments indicates this product is no longer in production. Engineers should consult official TI documentation for recommended replacement parts or next-generation alternatives within the optical driver portfolio. Direct pin-to-pin substitutes are not explicitly confirmed in public sources; system redesign may be necessary.
