Overview
The DS100KR800SQ/NOPB is an eight-channel unidirectional repeater from Texas Instruments, designed for high-speed serial data transmission. It supports data rates up to 10.3 Gbps per channel. The device integrates equalization and de-emphasis capabilities to compensate for signal loss in printed circuit board traces and cables. It operates within a supply voltage range of 2.375 V to 2.625 V and functions reliably across an industrial temperature range of -40°C to +85°C. The component is housed in a 54-pin WQFN package.
Feature Summary
- Eight independent channels provide high-density signal regeneration for multi-lane interfaces.
- Integrated adaptive equalization and programmable de-emphasis optimize signal integrity over lossy media.
- Unidirectional architecture simplifies system design for point-to-point or star-topology applications.
Applications
- High-speed backplane interconnects
- Storage area network (SAN) infrastructure
- Enterprise switch and router front panels
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference with the latest datasheet revision to identify any manufacturing changes or compliance updates before finalizing procurement specifications.
Selection Notes
Select this component when eight-channel unidirectional signal regeneration at 10.3 Gbps is required. Compare channel count and directionality against alternatives like the DS100BR series if bidirectional support is needed. Evaluate power consumption and thermal dissipation requirements relative to the 54-WQFN package constraints for the target enclosure design.
Part Context
This device belongs to the DS100KR family of high-speed repeaters. It complements other Texas Instruments interface solutions such as the DS100MB multiplexers and DS100BR redrivers. The family targets demanding enterprise and storage networking environments requiring robust signal conditioning across multiple lanes simultaneously.
Replacement Considerations
DS100KR800SQE/NOPB is a documented equivalent variant within the same product line. Verify package marking and internal configuration differences between SQ and SQE suffixes using official substitution guides before implementation.
