DS125DF111SQE

Specialized Overview

The DS125DF111SQE is a low-power, dual-channel retimer manufactured by Texas Instruments. It supports data rates up to 12.5 Gbps and operates on a single 2.5 V supply voltage. The device is housed in a WQFN-24 package with surface-mount installation. It functions as a signal buffer and repeater for interface applications. The component operates within a temperature range of -40°C to +85°C. It includes I2C serial interface capabilities for configuration.

Specialized Feature Summary

• Dual-channel architecture designed for high-speed signal regeneration
• Low power consumption optimized for energy-efficient systems
• Integrated clock and data recovery (CDR) functionality
• Configurable via I2C serial interface

Specialized Applications

• Front port interconnects
• Backplane communication links

Specialized Procurement Notes

Verify the specific suffix SQE against the manufacturer's datasheet to confirm package type and moisture sensitivity level. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm that the 2.5 V supply voltage aligns with the system design constraints before procurement.

Specialized Selection Notes

Select this component when dual-channel retiming at speeds up to 12.5 Gbps is required. It is suitable for designs needing low power dissipation in a compact WQFN-24 footprint. Consider the I2C control interface requirements for system integration. Verify that the application environment stays within the specified thermal limits.

Specialized Part Context

This part belongs to the DS125DF111 series of retimers from Texas Instruments. It is categorized under interface signal buffers and repeaters. The device is distinct from the DS125BR111, which is a repeater rather than a retimer. The series targets high-speed serial link applications requiring signal integrity restoration.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the DS125DF111 variants with different suffixes only if they share identical electrical specifications and pinouts as per the official datasheet.
