DS160PR410RNQR Overview
A redriver is a signal-conditioning device that sits between a transmitter and receiver on a high-speed serial link to compensate for channel loss. It uses continuous-time linear equalizers (CTLE) to apply frequency-dependent gain that restores the high-frequency components attenuated by the PCB trace, connector, and cable. The DS160PR410's CTLE boosts up to 18 dB at 8 GHz, which extends channel reach beyond what a passive link budget would normally allow. The device also includes automatic receiver detection tailored to PCIe use cases, allowing seamless insertion on a powered link.
Key features of the DS160PR410RNQR include CTLE boost up to 18 dB at 8 GHz, automatic receiver detection for PCIe, integrated termination, individual channel enable/disable via I2C or pin strap, low latency suitable for forward and reverse direction signaling, and 3.3 V single-supply operation. The device is protocol agnostic, meaning it can be repurposed for any AC-coupled, NRZ differential interface up to 25 Gbps without protocol-specific state machines.
The architecture uses a linear equalizer at each input followed by a limiting or linear output driver. Unlike retimers, redrivers do not require clock-data recovery (CDR) and do not add protocol latency, making them ideal for PCIe-compliant systems where every nanosecond of added latency must be accounted for in link training. The DS160PR410 supports both linear and limiting modes, giving designers flexibility between preserving multi-level eye characteristics or maximizing output swing.
Typical applications include server and workstation motherboards, NVMe SSD riser cards, backplanes, and riser cards that need to recover PCIe signal integrity across long trace routes or through connectors. Industrial and embedded computing platforms with PCIe over cable also benefit. Because the device is protocol agnostic, it can be used for UPI 2.0, SATA, SAS, and other AC-coupled NRZ interfaces up to 25 Gbps.
When designing with the DS160PR410RNQR, AC-coupling capacitors must be placed on the upstream transmit side of each redriver channel. The device supports SMBus/I2C control for fine-grained CTLE adjustment, or pin-strap configuration for simple deployment. Layout should keep high-speed differential traces length-matched within the channel and use 85 ohm differential impedance.

Typical Applications
DS160PR410RNQR is suitable for 6 applications: Server Motherboard PCIe Gen-4 Redriving, NVMe SSD Riser Card Signal Recovery, PCIe Backplane Signal Conditioning, Embedded Computing / Industrial PCIe Links, UPI 2.0 / High-Speed NRZ Redriving, Test and Measurement PCIe Card Design.
Server Motherboard PCIe Gen-4 Redriving
The DS160PR410RNQR's 4-channel architecture and 18 dB CTLE at 8 GHz make it ideal for compensating PCB trace and connector losses on server motherboards carrying PCIe Gen-4 (16 Gbps) signals. Per the TI datasheet, the device sits between the root complex and the PCIe slots, restoring signal integrity across slots that would otherwise fail link training. Its near-zero added latency is essential for maintaining PCIe compliance, and automatic receiver detection supports hot-plug and riser-card use cases.
Recommended
NVMe SSD Riser Card Signal Recovery
The DS160PR410RNQR's small 6x4 mm WQFN footprint and protocol-agnostic operation up to 25 Gbps suit it perfectly for NVMe SSD riser cards that extend PCIe Gen-4 from a baseboard connector. Per the TI datasheet, the CTLE compensates the connector and trace losses that would otherwise close the PCIe Gen-4 eye. The four channels map to a single x4 link, and the 3.3 V single-supply rail simplifies power sequencing on the riser card.
Recommended
PCIe Backplane Signal Conditioning
Per the TI datasheet, the DS160PR410RNQR's CTLE boost of up to 18 dB at 8 GHz allows it to redrive PCIe signals across long backplane traces and high-density connectors that would otherwise violate PCIe 4.0 link budgets. The four channels can be assigned to four lanes of a single Gen-4 slot, and pin-strap configuration eliminates the need for an SMBus host on simple backplanes. Operating temperature of -40C to +85C supports industrial chassis environments.
Recommended
Embedded Computing / Industrial PCIe Links
The DS160PR410RNQR's protocol-agnostic capability and -40C to +85C industrial temperature range suit it for embedded computing platforms that need PCIe over cable or extended trace runs in factory environments. Per the TI datasheet, the device redrives both PCIe Gen-4 and proprietary AC-coupled NRZ interfaces up to 25 Gbps, making it useful for industrial cameras, machine-vision frame grabbers, and test-and-measurement PCIe cards.
Recommended
UPI 2.0 / High-Speed NRZ Redriving
Per the TI datasheet, the DS160PR410RNQR is explicitly qualified for Ultra Path Interface (UPI) 2.0 operation up to 25 Gbps, in addition to PCIe. UPI is used in multi-socket server coherent fabrics. The redriver's linear architecture preserves the UPI link-training sequence, and the four channels support two full UPI links per device in many socket-to-socket topologies, helping engineers extend UPI reach across the CPU package and motherboard traces.
Recommended
Test and Measurement PCIe Card Design
Test and measurement instruments that expose PCIe Gen-4 to the host PC benefit from the DS160PR410RNQR's transparent signal conditioning. Per the TI datasheet, the redriver preserves eye characteristics while compensating for the long host-card trace and any interposers, allowing precise data acquisition and arbitrary-waveform-generator cards to meet PCIe 4.0 compliance. SMBus/I2C control enables per-channel CTLE tuning during card bring-up and validation.

- Automatic PCIe receiver detection (vs DS160PR410RNQT)
Design Notes
Per the TI datasheet, the WQFN-40 (RNQ) exposed thermal pad must be soldered to a continuous ground plane, both for thermal dissipation and for signal return-path integrity. Keep high-speed differential traces length-matched within each PCIe lane (typically within 5 mils), use 85-ohm differential impedance, and place AC-coupling capacitors on the upstream (TX-side) of each redriver channel as close to the device pins as possible.
Estimated: at 16 Gbps PCIe Gen-4, the Nyquist frequency is 8 GHz. The DS160PR410's CTLE provides up to 18 dB boost at 8 GHz, which can typically compensate ~12-15 inches of FR4 plus two high-speed connector crossings. Beyond that, eye margin may degrade; consider DS160PR822 (Gen-5 redriver with retimer options) for longer channels. Always verify with TDR and eye-diagram measurements on the actual PCB.
Per the TI datasheet, do not place the DS160PR410 too close to switching DC-DC converters; the CTLE is broadband and can amplify noise from nearby switching nodes. Add a small ferrite bead or pi-filter on the 3.3 V supply rail close to the device. Also, ensure the SMBus address strap (ADDR pin) is set correctly; an incorrect strap will cause the host to lose communication with the redriver and disable CTLE programming.
The WQFN-40 (RNQ) package has four high-speed channel groups (A, B, C, D). To minimize crosstalk, route channel pairs with at least 3W spacing between adjacent differential pairs, and avoid routing any high-speed traces under the device or across the exposed pad. Use a symmetrical breakout pattern so each lane sees the same via and trace geometry.
