DS38EP100SD

Specialized Overview

The DS38EP100SD is a passive equalizer designed for backplane and cable applications, supporting data rates from 1 to 5 Gbps. Manufactured by Texas Instruments (originating from the National Semiconductor portfolio), this component operates within an industrial temperature range of -40°C to +85°C. It is housed in a compact 6-pin WSON package, suitable for surface-mount installation. The device functions as a single-channel equalizer, providing signal integrity enhancement for high-speed serial links without requiring active power consumption for its core equalization function.

Specialized Feature Summary

• Supports data transmission speeds up to 5 Gbps for high-bandwidth applications
• Designed specifically for signal restoration in backplane and cable environments
• Operates reliably across extended industrial temperature ranges

Specialized Applications

• Backplane signal equalization
• Cable link signal conditioning
• High-speed serial communication interfaces

Specialized Procurement Notes

Verify the manufacturer designation carefully, as the component originates from National Semiconductor but is currently distributed under the Texas Instruments brand. Confirm the specific suffix requirements for packaging and environmental compliance during sourcing. Ensure the procurement channel provides authentic documentation matching the DS38EP100SD part number to avoid counterfeit risks associated with legacy semiconductor lines.

Specialized Selection Notes

Select this component when passive equalization is required for 1-5 Gbps signals in constrained spaces. The 6-WSON package offers a small footprint compared to larger SOIC options. Consider the thermal performance within the -40°C to +85°C range if operating in harsh environments. Verify that the passive nature of the equalizer meets the power budget constraints of the target design.

Specialized Part Context

This part belongs to the DS38EP100 series of equalizers. It shares functional similarities with other members like the DS38EP100SD/NOPB, differing primarily in packaging or environmental specifications. The transition from National Semiconductor to Texas Instruments means datasheets may reflect TI branding while retaining the original NS part numbering for compatibility.

Specialized Replacement Considerations

The DS38EP100SD/NOPB is a direct equivalent offering identical functionality with explicit lead-free confirmation. Other variants in the DS38EP100 family may provide alternative packaging options. Cross-reference pinouts and electrical characteristics before substituting with non-TI/National components.
