MPN: PS8936 ✓ NakahandaPS8936 Ulas
What is a retimer? A retimer is a mixed-signal device placed in series on a high-speed serial link that reconditions a degraded signal using a Clock and Data Recovery (CDR) circuit and re-transmits a clean, retimed waveform to the next segment. Retimers sit between simple redrivers (which are analog equalizers without CDR) and protocol-aware re-drivers; they add link-training transparency and a small, deterministic latency while fully recovering the eye diagram across long PCB traces, backplanes, or cables. PS8936 belongs to the signal-conditioning IC family within the broader high-speed serial interface IC category used in PCIe, CXL, USB, SATA, and Ethernet platforms.
Key features include 16 bidirectional lanes (32 channels total), PCIe 5.0 compliance at 32 GT/s, CXL 1.1/2.0 support, backward compatibility with PCIe 1.0/2.0/3.0/4.0 data rates, a low-latency forwarding path demonstrated as best-in-class in 2023, and integrated link training. The device is offered as PS8936BGA354GTR-A1 in tape-and-reel packaging and is supported by a PS8936-EVB evaluation board and a PS8936-DEBUG BOARD reference design. It is qualified on the PCI-SIG integrator list as a PCIe Gen5 x16 32 Gbps retimer, simplifying compliance validation for OEMs.
Typical applications include AI accelerator and GPU server backplanes, NVMe Gen5 storage controllers, CXL type-3 memory pooling switches, hyperscale rack-scale fabrics, workstation motherboards with multi-slot PCIe Gen5 topologies, and accelerator card risers that need long reach over the top of the board. Its low-latency behavior matters for coherent memory and accelerator fabrics where every nanosecond added by conditioning reduces effective bandwidth.
When designing with PS8936, pay close attention to PCB stack-up, reference-clock routing, and decoupling; the 354-ball BGA package demands a symmetrical escape pattern and a contiguous ground reference. Pair it with a low-jitter 100 MHz reference clock and follow the reference schematic in the PS8936-EVB evaluation kit to ensure first-pass compliance.

AI Accelerator Server Backplanes
The PS8936's 16 bidirectional lanes at 32 Gbps with low-latency forwarding make it ideal for AI training systems that need x16 PCIe Gen5 connectivity between GPUs, NVMe Gen5 storage, and CXL memory pools. Per StorageNewsletter 2023-08-04, PS8936 demonstrated the lowest latencies in the industry for a Gen5 retimer, a critical factor in coherent accelerator fabrics where every nanosecond of added conditioning reduces effective bandwidth. Reference design: PS8936-EVB.
Inirekomenda
Enterprise NVMe Gen5 Storage Controllers
The PS8936 supports PCIe 5.0 at 32 GT/s with backward compatibility to PCIe 1.0/2.0/3.0/4.0 data rates, making it ideal for enterprise NVMe Gen5 storage controllers that must interface with both new host CPUs and legacy backplanes. Its 32 data channels enable full x16 host-facing links while maintaining signal-integrity margins over long M.2-to-PCIe adapter traces common in dense storage enclosures.
Inirekomenda
CXL Type-3 Memory Pooling Switches
The PS8936 supports Compute Express Link (CXL) 1.1 and 2.0 alongside PCIe 5.0, enabling CXL type-3 memory pooling switches that aggregate DRAM and persistent memory across a rack. Per the StorageNewsletter 2023-01-26 announcement, the PS8936 retimer was specifically developed for PCIe 5.0 and CXL, giving system designers a single retimer that covers both protocols without separate silicon.
Inirekomenda
Hyperscale Rack-Scale Fabric Interconnects
The PS8936's 32 Gbps per lane and low-latency forwarding path suit hyperscale rack-scale fabrics that disaggregate compute, memory, and storage. Each retimer instance recovers a clean eye diagram across backplane connectors and long traces, allowing Gen5 signaling to traverse distances that would otherwise force a downgrade to Gen4 - directly preserving rack-level bandwidth density for cloud providers.
Inirekomenda
Workstation Motherboards with Multi-Slot Gen5 Topology
The PS8936's 16-lane configuration is ideal for workstation motherboards that need multiple Gen5 x16 slots for GPUs and accelerators. Per the Parade product brief, it is targeted at applications incorporating high lane count PCIe bus widths such as workstations. The BGA-354 package supports dense PCB escape patterns needed for multi-slot topologies.
Inirekomenda
Accelerator Card Risers and Add-In Cards
The PS8936 enables long-reach PCIe Gen5 signaling on accelerator card risers and add-in cards where the host slot sits far from the local silicon. CDR-based signal recovery restores the eye diagram across PCB bends and connector crossings that would otherwise exceed Gen5 loss budgets. Reference design PS8936-EVB demonstrates a typical riser implementation with the 354-ball BGA.

Talaan ng Disenyo
The PS8936 ships in a 354-ball BGA package requiring a symmetrical escape pattern and a contiguous ground reference. Route all 32 high-speed differential pairs with matched lengths within the budget specified in the PS8936-EVB reference design. Use a 4-6 layer stack-up with low-loss dielectric (Df < 0.005 at 8 GHz) to preserve Gen5 eye margins.
Provide a low-jitter 100 MHz reference clock with phase noise below -120 dBc/Hz at 10 kHz offset. Place the reference clock generator within 25 mm of the PS8936 clock input pins and maintain 50 ohm single-ended impedance. Reference-clock jitter directly multiplies into retimer output jitter and will close the Gen5 link-training eye.
Estimated: at 32 Gbps across 32 active channels with typical 8 pJ/bit power, the PS8936 dissipates approximately 8 W under full bidirectional load. Provide a thermal pad array beneath the BGA connected to an inner ground plane, and ensure 200 LFM of airflow or attach a small heatsink to keep junction temperature below 105 C.
Decouple each power rail with 0.1 uF X7R ceramic capacitors placed within 2 mm of the BGA balls, plus bulk 10 uF and 22 uF capacitors per rail. Separate analog and digital ground returns to a single star point beneath the IC. Avoid routing any high-speed lanes across plane splits, which would severely degrade Gen5 return loss.
Do not substitute a redriver for the PS8936 on long PCIe Gen5 traces - redrivers lack CDR and will fail compliance on lossy channels. Always validate the design with the PS8936-EVB schematic and PCB layout before tape-out, and verify with a PCIe Gen5 compliance test load at your test house.
