DS125RT410SQE/NOPB

Specialized Overview

The DS125RT410SQE/NOPB is a quad-channel retimer designed for high-speed serial data transmission. It supports data rates from 9.8 Gbps to 12.5 Gbps, making it suitable for PCI Express and SAS applications. The device integrates adaptive equalization and a clock data recovery (CDR) circuit to restore signal integrity over lossy channels. It operates on a single 2.5 V supply voltage and functions within an ambient temperature range of -40°C to +85°C. The component is housed in a 48-pin WQFN package with exposed pad for thermal management.

Specialized Feature Summary

• Integrates adaptive equalization to compensate for channel loss
• Includes clock data recovery circuit for signal regeneration
• Supports front port and backplane connectivity architectures

Specialized Applications

• PCI Express interconnect systems
• SAS storage backplanes
• High-performance server infrastructure

Specialized Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and lead-free status. Confirm that the specific revision matches the design requirements. Check manufacturer documentation for moisture sensitivity level handling procedures. Ensure ESD protection protocols are followed during assembly. Validate compatibility with system power supply specifications before integration.

Specialized Selection Notes

Select this component when signal degradation requires active regeneration rather than passive buffering. The integrated CDR eliminates the need for external clock sources in many configurations. Consider the thermal performance of the WQFN package in dense layouts. Verify that the input signal amplitude meets the receiver sensitivity requirements. Evaluate channel loss characteristics to determine if adaptive equalization is necessary.
