Overview
The DS160PR421RUAR is a four-channel linear redriver with an integrated 2:1 multiplexer designed for PCIe 4.0 and other high-speed interfaces up to 16 Gbps. It operates on a single 3.3 V supply rail within the -40°C to +85°C industrial temperature range. The device provides up to 17 dB of equalization at 8 GHz, handles up to 42 dB of channel loss, and features low additive random jitter of 70 fs with PRBS data. It includes automatic receiver detection, seamless PCIe link training support, and configuration via pin control or SMBus/I2C.
Feature Summary
- Integrates four-channel linear redriver functionality with a 2:1 multiplexer for signal path selection.
- Supports protocol-agnostic operation for PCIe 4.0, UPI, DisplayPort, SAS, SATA, and XFI.
- Features continuous-time linear equalizers (CTLE) to compensate for inter-symbol interference in passive channels.
- Includes internal linear voltage regulators to provide clean power for high-speed data paths.
Applications
- Desktop PC/motherboard
- Rack server
- Microserver & tower server
- High performance computing
- Hardware accelerator
Procurement Notes
Verify the specific ordering suffix RUAR corresponds to the WQFN-42 package and Reel/Cut Tape packaging options as documented. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the procurement source provides valid datasheets and traceability documentation consistent with Texas Instruments production standards.
Selection Notes
Select this component when designing systems requiring PCIe 4.0 signal integrity extension over PCB traces or cables. Consider the integrated 2:1 mux capability if port expansion or redundancy is required. Evaluate the low active power consumption per channel against thermal constraints. Verify compatibility with the system's I2C/SMBus controller or strap-pin configuration logic.
Part Context
The DS160PR421 belongs to the DS160PR4xx series of linear redrivers from Texas Instruments. It is specifically engineered for high-speed serial interface applications where signal degradation over passive interconnects must be mitigated. The device complements companion demultiplexer products like the DS160PR412 in complex routing architectures.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official product change notification or obsolescence notices for potential replacements.
FAQ
How does the DS160PR421 handle polarity inversion?
The device does not have registers for polarity inversion. Polarity conversion is handled by the protocol layout in PCIe applications.
What is the maximum equalization boost provided by the CTLE?
The device provides equalization up to 17 dB at 8 GHz to handle significant channel loss.
Can the device be configured without an I2C master?
Yes, the device supports Pin Mode where configuration is done solely by strap pins such as MODE, EQ0, EQ1, and GAIN.
