DS280MB810ZBLT

Signal Buffers, Repeaters, Splitters Overview

The DS280MB810ZBLT is an eight-channel linear repeater designed for high-speed serial data transmission applications operating at rates up to 28 Gbps. It functions as a signal conditioning device that amplifies and equalizes differential signals without clock recovery, thereby extending the effective reach of SerDes links across lossy backplanes and cables. The component utilizes a low-power architecture suitable for dense system designs. It features programmable equalization settings to compensate for channel attenuation and includes a crosspoint switch for flexible signal routing. The device operates within a supply voltage range of 2.5 V to 3.3 V and supports SPI interface configuration.

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 existing board layout constraints regarding the FCCSP-135 package. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Validate that the procurement source provides genuine TI components to avoid counterfeit risks associated with high-frequency mixed-signal ICs.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when low latency and rate transparency are prioritized over jitter cleaning capabilities provided by retimers. Evaluate power consumption requirements against the thermal budget of the enclosure. Consider the need for external EEPROM or I2C/SPI master for configuration storage. Assess channel count needs; if fewer lanes are required, verify if lower-density variants offer cost advantages while meeting performance targets.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS280 family of high-speed interface solutions from Texas Instruments. It complements retimer devices like the DS280DF810 by offering a linear alternative for scenarios where jitter accumulation is manageable but signal amplitude restoration is critical. The family targets next-generation 25G/28G NRZ systems, providing engineers with modular building blocks for scalable high-bandwidth architectures.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct pin-to-pin replacements may include other TI linear redrivers within the same series. Verify electrical parameters such as insertion loss tolerance and crosstalk specifications before substituting. Cross-reference with competitor offerings only if form-factor and interface protocols match exactly.
