Overview
The DS160PR412RUAR is a four-channel linear redriver designed for PCI Express applications, manufactured by Texas Instruments. It supports data rates up to 16 Gbps and operates within a supply voltage range of 3 V to 3.6 V. The device features input equalization and output de-emphasis capabilities to maintain signal integrity over lossy channels. It is housed in a 42-WQFN package with dimensions of 3.5 mm by 9 mm. The component functions as a buffer and retimer driver, utilizing LVCMOS inputs and differential outputs. It operates reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Provides four independent channels for high-speed signal conditioning
- Integrates input equalization and output de-emphasis for signal restoration
- Supports PCIe 4.0 interface standards with 16 Gbps per lane capability
Applications
- PCI Express signal integrity enhancement
- High-speed digital interconnect buffering
- Server and storage system backplanes
Procurement Notes
Verify the specific suffix RUAR against official datasheets to confirm the tape and reel packaging configuration. Ensure compatibility with standard surface mount assembly processes. Confirm that the 42-WQFN footprint matches the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring passive signal regeneration for PCIe links. Compare channel count and power consumption against alternative redrivers. Verify that the operating voltage range aligns with the system's power delivery network specifications.
Part Context
This part belongs to the DS160PR412 series of linear redrivers from Texas Instruments. It is functionally related to the DS160PR421, which shares similar architectural characteristics but may differ in specific pinout or feature sets. The series addresses signal degradation issues in high-speed serial interfaces.
Replacement Considerations
The DS160PR412RUAT is listed as a parameter-equivalent substitute. Verify pin-to-pin compatibility and electrical specifications before swapping these variants.
