DS125BR401ANJYT

Overview

The DS125BR401ANJYT is a low-power, four-lane linear repeater manufactured by Texas Instruments. It supports data rates up to 12.5 Gbps and operates with supply voltages of 2.5 V or 3.3 V. The device features input equalization and output de-emphasis capabilities to extend link distance in high-speed serial applications. It is housed in a 54-pin NJY package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Four-channel linear repeater architecture for signal regeneration
• Configurable input equalization and output de-emphasis settings
• Dual voltage operation supporting 2.5 V and 3.3 V supplies

Applications

• PCI Express (PCIe) interconnects
• SAS-3 storage interfaces
• SATA peripheral connections

Procurement Notes

Verify the specific suffix ANJYT against official datasheets to confirm pinout and package dimensions. Ensure compatibility with existing board layouts and thermal management requirements before procurement.

Selection Notes

Select this component for designs requiring four lanes of signal buffering at speeds up to 12.5 Gbps. Confirm that the system power budget accommodates the device's current consumption at the chosen supply voltage.

Part Context

This part belongs to the DS125BR401 family of high-speed repeaters. It serves as a signal conditioner for extending trace lengths in backplane and front-panel applications where signal integrity is critical.

Replacement Considerations

DS125BR401SQ/NOPB is a documented alternative in the same series. Verify package compatibility and electrical specifications before substitution.
