ONET4251PARGTT

Overview

The ONET4251PARGTT is a limiting amplifier manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates ranging from 1 Gbps to 4.25 Gbps. The device integrates Loss of Signal (LOS) detection and Received Signal Strength Indicator (RSSI) functionality for system monitoring. It is housed in a 16-pin HVQCCN package with dimensions of 3 mm. The component operates within an extended temperature range of -40 °C to +85 °C. It complies with RoHS standards and contains no lead.

Feature Summary

• Supports data transmission speeds from 1 Gbps up to 4.25 Gbps
• Integrates Loss of Signal detection capability
• Includes Received Signal Strength Indicator output

Applications

• High-speed serial communication links
• Optical transceiver modules
• Telecommunications equipment

Procurement Notes

Verify the specific ordering suffix 'GTT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets the required environmental operating range of -40 °C to +85 °C for the intended application. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.

Selection Notes

Select this component when a limiting amplifier with integrated signal monitoring is required for data rates up to 4.25 Gbps. The choice depends on the necessity for LOS and RSSI features within a compact 16-pin QFN form factor. Verify that the electrical characteristics align with the specific interface requirements of the target system design.

Part Context

This part belongs to the ONET4251 family of limiting amplifiers produced by Texas Instruments. It shares functional similarities with the ONET4251PARGTR variant, differing primarily in packaging or reel configuration. The device serves as a key component in high-bandwidth signal conditioning applications requiring precise amplitude control.

Replacement Considerations

The ONET4251PARGTR is listed as a related component with identical functional descriptions. Verify pinout compatibility and package dimensions before substitution.
