DS125BR800ANJYR

Overview

The DS125BR800ANJYR is a low-power, high-performance 8-channel repeater manufactured by Texas Instruments. It supports data rates up to 12.5 Gbps and is designed for signal integrity in high-speed serial interfaces. The device features continuous time linear equalization (CTLE) at the receiver and adjustable de-emphasis at the transmitter. It operates on a single 2.5 V or 3.3 V supply voltage. The component is housed in an NJYR package and functions as a redriver for PCIe, SAS, and SATA protocols.

Feature Summary

• Provides eight channels of signal regeneration with input equalization and output de-emphasis capabilities.
• Supports multiple high-speed interface standards including PCIe Gen1/Gen2/Gen3 and SAS/SATA protocols.
• Features low power consumption per channel with the ability to disable unused channels.

Applications

• Enterprise server backplane interconnects
• Storage area network (SAN) equipment
• Peripheral I/O expansion systems

Procurement Notes

Verify the specific suffix ANJYR against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system power requirements and thermal management constraints before procurement.

Selection Notes

Select this component when eight independent signal paths are required for 12.5 Gbps applications. Consider the single-supply operation and I2C configuration interface for system integration flexibility compared to multi-supply alternatives.

Part Context

This part belongs to the DS125BR800 family of ultra-low power repeaters. It serves as a signal conditioning solution for extending reach in copper-based high-speed serial links within data center and enterprise infrastructure environments.

Replacement Considerations

Check for DS125BR800 variants with different suffixes that may offer identical electrical performance but distinct packaging options. Verify pinout compatibility if substituting with other members of the DS125BR series.
