What are the key features of DS80PCI800SQE/NOPB?
- 8-channel PCI Express repeater supporting 2.5 Gbps (Gen1), 5.0 Gbps (Gen2), and 8.0 Gbps (Gen3) per lane for broad PCIe compatibility
- Integrated continuous-time linear equalization (CTLE) and programmable de-emphasis restoring signal integrity across lossy PCB traces or backplane channels
- Compact QFN-54 package with fully differential I/O architecture enabling high-density server and storage backplane designs
What is DS80PCI800SQE/NOPB used for?
The DS80PCI800SQE/NOPB is designed for PCIe signal conditioning in servers, storage systems, and high-performance computing platforms where signals must travel across long FR4 traces or cable interconnects. Its 8 channels of equalization and de-emphasis allow system designers to extend PCIe Gen3 8 Gbps links beyond typical trace length limits without retimers. It is also used in test equipment backplanes and industrial computing chassis requiring reliable high-speed differential signal restoration.

Frequently Asked Questions
Which PCIe generations does DS80PCI800SQE/NOPB support and at what per-lane data rates?
DS80PCI800SQE/NOPB supports PCIe Gen1 at 2.5 Gbps, Gen2 at 5.0 Gbps, and Gen3 at 8.0 Gbps per lane across all 8 differential channels. This multi-generation compatibility allows the same repeater design to work in platforms spanning PCIe Gen1 legacy cards through Gen3 high-speed NVMe or GPU interconnects.
How does DS80PCI800SQE/NOPB restore signal integrity across lossy PCB traces?
DS80PCI800SQE/NOPB applies continuous-time linear equalization (CTLE) to compensate for high-frequency attenuation in FR4 PCB traces, and programmable de-emphasis to reduce inter-symbol interference at the far end. This allows PCIe Gen3 8 Gbps signals to travel over traces or cables that would otherwise cause unacceptable bit error rates without active conditioning.
For which server or storage backplane designs does the DS80PCI800SQE/NOPB QFN-54 package provide the best fit?
The DS80PCI800SQE/NOPB in QFN-54 is well-suited for high-density server backplanes, storage arrays, and PCIe switch cards where 8 lanes of Gen3 signal conditioning must fit in minimal board area. Its compact footprint and differential I/O architecture support multi-slot expansion chassis and JBOD storage enclosures requiring reliable 8.0 Gbps lane integrity.
When should DS80PCI800SQE/NOPB be chosen over a PCIe redriver or retimer for signal extension?
DS80PCI800SQE/NOPB, as a repeater with equalization and de-emphasis, is preferred when signal loss is moderate and latency must be minimized versus a full retimer. For PCB trace lengths where 8 Gbps eye diagrams are marginal but not fully closed, the DS80PCI800 restores signal quality at lower power and latency than a clock-data recovery retimer solution.
