DS100BR111ASQ/NOPB

Overview

The DS100BR111ASQ/NOPB is a two-channel ultra-low power redriver manufactured by Texas Instruments. It supports data rates up to 10.3 Gbps and operates within a supply voltage range of 2.5 V to 3.3 V. The device features AC-coupled CML inputs and outputs, with an input capacitance of 10 pF and a propagation delay of 230 ps. It functions as a signal buffer and repeater for high-speed serial interfaces. The component is housed in a 24-pin WQFN package and is rated for operation between -40°C and +85°C.

Feature Summary

• Provides signal integrity restoration for high-speed serial links through active equalization.
• Supports standard CML signaling formats with AC coupling capabilities on both input and output channels.
• Integrates I2C control interface for configuration management and status monitoring.

Applications

• Front port interconnects in storage and networking equipment
• Backplane signal distribution systems
• Peripheral I/O expansion modules

Procurement Notes

Verify the specific suffix 'SQ' against the manufacturer's official documentation to confirm moisture sensitivity level and reel packaging specifications. Ensure the NOPB designation aligns with current RoHS compliance requirements for the target assembly process. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 10.3 Gbps throughput with low power consumption constraints. Compare input capacitance and propagation delay against system timing budgets. Verify that the WQFN-24 package footprint matches the PCB layout constraints and thermal dissipation requirements of the application environment.

Part Context

This part belongs to the DS100BR111A series of high-speed redrivers from Texas Instruments. It shares functional similarities with the DS64BR111 and DS125BR111 models but is optimized specifically for 10.3 Gbps applications. The series provides standardized solutions for signal regeneration in complex electronic architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative Texas Instruments redriver models based on channel count and speed requirements if direct substitution is necessary.
