DS280BR820ZBLR

Signal Buffers, Repeaters, Splitters Overview

The DS280BR820ZBLR is an eight-channel linear repeater manufactured by Texas Instruments, designed for low-power signal integrity applications. It supports data rates up to 12.5 Gbps per channel and operates within a supply voltage range of 2.5 V to 3.3 V. The device integrates input equalization capabilities to compensate for channel loss in high-speed serial links. Packaged in a compact ZBLR format, it utilizes an I2C interface for configuration and control. This component is engineered to maintain signal quality across PCB traces and backplanes in demanding digital communication environments.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix ZBLR against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts and power delivery networks before procurement. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current availability status.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when eight-channel linear repeater functionality is required at data rates up to 12.5 Gbps. Consider the integrated input equalization feature if the application involves significant trace loss. Verify that the operating temperature range and supply voltage requirements align with the target system design constraints.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS280BR series of linear repeaters from Texas Instruments. It is distinct from retimers as it focuses on linear amplification rather than clock recovery. The ZBLR suffix indicates a specific surface-mount package variant suitable for automated assembly processes in high-volume manufacturing environments.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct replacements may include other eight-channel linear repeaters from the same family, such as the DS280BR820 or DS280BR810, provided pinout and electrical characteristics are compatible. Verify functional equivalence regarding equalization settings and power consumption before substitution.
