Overview
The DS125BR401ANJYR is a low-power, four-channel linear repeater manufactured by Texas Instruments. It supports data rates up to 12 Gbps and is designed for high-speed serial interfaces including PCIe, SAS, and SATA. The device integrates input equalization and output de-emphasis to compensate for channel loss. It operates within a supply voltage range of 2.375 V to 3.6 V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in a compact NJY package.
Feature Summary
- Integrates continuous-time linear equalization (CTLE) at the input stage to mitigate high-frequency signal attenuation.
- Features programmable output de-emphasis to optimize signal integrity for long trace applications.
- Supports multiple industry-standard protocols including PCI Express, Serial Attached SCSI, and Serial ATA.
Applications
- PCI Express Gen 3 backplane interconnects
- SAS/SATA storage expansion enclosures
- Peripheral I/O signal conditioning
Part Context
This component belongs to the DS125BR401 family of linear redrivers. It serves as a signal regeneration solution for high-speed serial links where passive copper traces introduce significant insertion loss. The device maintains signal fidelity without requiring complex retiming circuitry, offering a power-efficient alternative for standard repeater applications.
Replacement Considerations
Publicly confirmed substitute part numbers include DS125BR401SQE/NOPB and DS125BR401A variants. Designers should verify pin compatibility and thermal performance when transitioning between package types such as WQFN and NJY.
