DS125BR820NJYT

Overview

The DS125BR820NJYT is a low-power, 12.5-Gbps linear repeater featuring eight independent channels in a single package. Designed for high-speed serial data transmission, it supports data rates up to 12.5 Gbps with a propagation delay of 70 ps. The device operates on a supply voltage range of 2.375 V to 3.6 V and functions within an ambient temperature range of -40°C to +85°C. It utilizes a WQFN-24 package suitable for surface-mount applications. Key electrical characteristics include an input capacitance of 5 pF and a typical operating current of 52 mA per channel.

Feature Summary

• Eight-channel linear repeater architecture supporting high-density signal routing
• Ultra-low power consumption optimized for thermal-constrained environments
• Integrated input equalization and output de-emphasis capabilities
• AC-coupled CML input and output interfaces for direct connectivity

Applications

• Front panel interconnects in server and storage systems
• Backplane signal extension in high-speed networking equipment
• Peripheral I/O expansion for PCIe and SAS/SATA interfaces

Procurement Notes

Verify the specific suffix NJYT against official Texas Instruments documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure that the procurement source provides valid RoHS compliance certificates and moisture sensitivity level ratings prior to ordering. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when eight-channel signal regeneration is required without the complexity of retiming circuitry. The DS125BR820NJYT is appropriate for designs needing adjustable equalization to compensate for channel loss. Compare power dissipation requirements against available board space and cooling solutions. Confirm that the system interface standards align with the device's CML AC-coupled specifications.

Part Context

This part belongs to the DS125BR8xx series of low-power linear repeaters from Texas Instruments. The series is engineered for high-speed serial link applications requiring signal integrity restoration over printed circuit board traces or backplanes. The DS125BR820 variant specifically offers eight channels, distinguishing it from lower-channel-count counterparts like the DS125BR111.

Replacement Considerations

The DS125BR800 and DS125BR800A are documented family members with similar 8-channel architectures. Verify functional equivalence regarding equalization settings and pin compatibility before substitution. Consult the latest TI datasheets to confirm any revisions in electrical characteristics or package dimensions.
