DS280BR820ZBLT

Signal Buffers, Repeaters, Splitters Overview

The DS280BR820ZBLT is a low-power, eight-channel linear repeater manufactured by Texas Instruments. It supports data rates up to 12.5 Gbps per channel and operates within a supply voltage range of 3.0 V to 3.6 V. The device features integrated input equalization to compensate for signal loss in high-speed serial links. Designed for surface-mount applications, it utilizes a compact FCCSP-135 package suitable for dense PCB layouts. The component includes an I2C interface for configuration and monitoring, ensuring reliable performance in demanding digital communication environments.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrated continuous-time linear equalization (CTLE) at the receiver input to mitigate channel attenuation
• Configurable via I2C interface for flexible system integration and real-time parameter adjustment
• Low power consumption design optimized for thermal management in multi-lane architectures

Signal Buffers, Repeaters, Splitters Applications

• High-speed backplane interconnects in enterprise servers and storage systems
• Data center switch and router board-to-board connections
• Telecommunications infrastructure requiring robust signal integrity over long traces
• Industrial automation control panels with high-frequency data transmission needs

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix ZBLT against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your system's I2C addressing scheme before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when eight-channel linear repeater functionality is required for 12.5 Gbps signals. Consider the FCCSP-135 package constraints during PCB layout planning. Evaluate power budget requirements as the device draws current proportional to the active channels and data rate. Compare against lower-speed alternatives like the DS125BR800A if data rates below 12.5 Gbps are sufficient for your application.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS280BR series of linear repeaters from Texas Instruments. It complements other devices in the family such as the DS280BR810, which supports higher speeds up to 28 Gbps. The series is designed to address signal integrity challenges in modern high-speed digital interfaces. Engineers often use these repeaters to extend trace lengths beyond standard limits without resorting to retimers.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS280BR820ZBFT is a functional equivalent with a different packaging option. Verify pinout compatibility and electrical characteristics before substitution. Other family members like the DS125BR820 offer similar performance but may differ in specific equalization settings or power profiles.
