DS320PR410RNQT

Signal Buffers, Repeaters, Splitters Overview

The DS320PR410RNQT is a four-channel linear redriver designed for PCIe 5.0, CXL 2.0, and UPI 2.0 interfaces operating up to 32 Gbps. It features continuous-time linear equalizers (CTLE) with boost up to 22 dB at 16 GHz and ultra-low latency of 100 ps. The device operates on a single 3.3 V supply with active power consumption of 160 mW per channel. It supports pin-strap, SMBus, or EEPROM programming and includes automatic receiver detection. The component is housed in a 4 mm × 6 mm, 40-pin WQFN package and functions within a temperature range of –40 °C to 85 °C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix RNQT against the manufacturer's current orderable addendum to confirm package type and reel specifications. Ensure compatibility with system requirements for the 40-pin WQFN footprint and thermal dissipation needs. Confirm that the intended application environment falls within the specified operating temperature range of –40 °C to 85 °C before finalizing procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing links requiring transparent signal conditioning for PCIe 5.0 or CXL 2.0 protocols. The device is suitable for extending trace lengths where passive channels suffer from significant insertion loss. Consider its low latency and protocol agnostic nature for applications demanding seamless link training without protocol-specific retiming overhead.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to Texas Instruments' PR410 family of linear redrivers. It serves as a signal integrity solution for high-speed serial interfaces, complementing other devices like the DS100RT410 and DS160PR410 which target lower speed generations such as PCIe 4.0. The DS320PR410 specifically addresses the higher frequency demands of next-generation computing standards.
