DS125BR820NJYR

Overview

The DS125BR820 is a low-power, eight-channel linear repeater manufactured by Texas Instruments. It supports data rates up to 12.5 Gbps and operates on a single 3.3V supply. The device features integrated input equalization and output de-emphasis for signal integrity optimization. It utilizes an NJYR package variant of the VQFN-64 form factor. Key electrical parameters include a maximum clock frequency of 6 GHz, propagation delay of 70 ps, and an operating temperature range from -40°C to +85°C.

Feature Summary

• Eight-channel architecture designed for high-density serial interface applications
• Integrated input equalization and output de-emphasis capabilities
• Low-power operation optimized for thermal efficiency in dense systems

Applications

• PCI Express Gen 3/4 backplane interconnects
• SAS/SATA storage expansion enclosures
• Peripheral I/O signal extension

Procurement Notes

Verify the specific suffix NJYR against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined by the manufacturer. Cross-reference ordering part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when eight independent channels are required for signal regeneration at speeds up to 12.5 Gbps. Consider the VQFN-64 package constraints for PCB layout and thermal dissipation requirements. Evaluate power consumption metrics against system thermal budgets compared to lower-channel-count alternatives.

Part Context

This device belongs to the DS125BR series of linear repeaters from Texas Instruments. It complements other models like the DS125BR800 but offers distinct packaging options. The series targets high-speed serial communication standards requiring robust signal conditioning without retiming.

Replacement Considerations

DS125BR800: Similar channel count and speed but may differ in package type or specific feature sets.
