DS320PR822NJXT

Overview

The DS320PR822NJXT is an eight-channel linear redriver designed for PCIe 5.0, CXL 2.0, and UPI 2.0 interfaces operating up to 32 Gbps. It features four independent 2x2 crosspoint muxes and continuous-time linear equalizers (CTLE) with boost up to 22 dB at 16 GHz. The device provides ultra-low latency of 100 ps and low additive random jitter of 75 fs. It operates on a single 3.3 V supply with internal voltage regulation for noise immunity. The component is housed in a 64-pin WQFN package measuring 5.5 mm by 10.0 mm.

Procurement Notes

Verify the specific ordering suffix NJXT corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure the procurement source is authorized to guarantee authenticity and traceability of the Texas Instruments semiconductor product.

Selection Notes

Select this component when designing systems requiring transparent signal regeneration for PCIe 5.0 or CXL 2.0 links. The integrated crosspoint mux functionality allows for flexible lane mapping without additional external switching components. Consider the low power consumption per channel when evaluating thermal management requirements for dense server or accelerator form factors.

Part Context

This part belongs to the DS320PR series of linear redrivers from Texas Instruments. The series is engineered to extend reach and integrity for high-speed serial data links. The DS320PR822 specifically targets applications needing multiple channels with independent equalization and routing capabilities within a compact footprint suitable for modern motherboard and mezzanine card designs.

Replacement Considerations

Consult the official datasheet orderable addendum for direct pin-compatible alternatives within the same family. Verify functional equivalence regarding data rates, channel count, and package dimensions before substitution.
