DS125RT410SQ/NOPB

Specialized Overview

The DS125RT410SQ/NOPB is a quad-channel retimer manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates ranging from 9.8 Gbps to 12.5 Gbps per channel. The device integrates adaptive equalization and a clock data recovery (CDR) circuit to regenerate signals with low jitter. It operates on a single 2.5 V power supply, drawing approximately 240 mA of operating current. The component is housed in a 48-WQFN package with exposed pad, suitable for surface mount installation. It functions within an industrial temperature range of -40°C to +85°C.

Specialized Feature Summary

• Integrates four independent channels for simultaneous signal regeneration
• Includes adaptive equalization and clock data recovery for signal integrity
• Supports I2C and SMBus interfaces for configuration and monitoring

Specialized Applications

• Front port interconnects in networking equipment
• Backplane connections in server architectures
• High-speed storage area networks

Specialized Procurement Notes

Verify the exact suffix against official Texas Instruments documentation to confirm package variant and tape-and-reel specifications. Ensure compatibility with system voltage requirements and thermal management constraints before procurement. Confirm moisture sensitivity level handling procedures are aligned with manufacturing standards.

Specialized Selection Notes

Select this component when designing systems requiring signal regeneration at speeds up to 12.5 Gbps. Consider the 48-WQFN footprint for PCB layout constraints. Evaluate thermal dissipation capabilities given the 2.5 V supply and typical current draw. Verify interface compatibility with host controllers using I2C or SMBus protocols.

Specialized Part Context

This part belongs to the DS125RT410 series of quad-channel retimers. It shares functional similarities with other devices in the family but is distinguished by its specific data rate support and packaging. The NOPB suffix indicates lead-free construction compliant with RoHS directives.

Specialized Replacement Considerations

DS125RT410SQE/NOPB is a documented equivalent variant within the same product line.
