DS100RT410SQE/NOPB

Specialized Overview

The DS100RT410SQE/NOPB is a quad-channel retimer designed for 10 Gigabit Ethernet applications, manufactured by Texas Instruments. It operates within a supply voltage range of 2.375 V to 2.625 V and consumes 240 mA of operating current. The device features a propagation delay of 300 ps and supports an I2C/SMBus interface with a maximum clock frequency of 400 kHz. It is housed in a 48-WQFN package with exposed pad, suitable for surface mount installation. The component functions reliably across an extended temperature range from -40°C to +85°C.

Specialized Feature Summary

• Provides signal regeneration for four independent channels to maintain data integrity over lossy transmission paths.
• Integrates adaptive equalization capabilities to compensate for channel attenuation and distortion.
• Includes built-in clock data recovery (CDR) circuits for precise timing alignment of output signals.
• Supports configuration and monitoring via standard I2C or SMBus digital interfaces.

Specialized Applications

• Front port interconnects in high-speed networking equipment
• Backplane connections in enterprise switches and routers
• Signal conditioning for 10Gb Ethernet links

Specialized Procurement Notes

Verify the complete part number including the suffix 'SQE/NOPB' to ensure correct package type and lead-free compliance. Confirm that the supplier provides original manufacturer documentation or test reports. Check for moisture sensitivity level requirements during storage and handling. Ensure the procurement source is authorized to avoid counterfeit components.

Specialized Selection Notes

Select this component when designing systems requiring 10Gb Ethernet signal integrity over significant trace lengths. Compare against similar retimers based on channel count and power consumption. Verify that the 48-WQFN footprint matches the PCB layout constraints. Ensure the control interface compatibility with the system controller's I2C/SMBus specifications.
