1. CUC0647B0514B is an x4-lane high-speed connector that complies with the PCI-SIG CEM 5.0 specification. It achieves a single-lane transmission rate of 32GT/s through a 64-pin configuration, and is specifically designed for mid-to-high-end storage, edge computing, and embedded systems. Its innovative "side-slotted + no side eaves" structure not only ensures high-speed signal integrity at 32GT/s, but also solves the installation challenges in confined space deployment, making it suitable for high-density equipment scenarios such as 1U servers and industrial motherboards.

2. Optimized Heat Dissipation Efficiency: The slotted structure expands the air convection area by over 30%. Compared with non-slotted designs, it reduces local temperature rise by 4-6℃ at a rate of 32GT/s, solving the heat accumulation issue in multi-lane signal transmission.Foolproof Design & Plug-in Assistance: The slot forms a mechanical interlock with the protruding structure of the device interface, improving plug-in positioning accuracy to ±0.1mm, reducing the incorrect insertion rate by 90%, and minimizing gold finger wear at the same time.

3. Space Adaptation Advantage of No Side EavesReduced Installation Space: After eliminating the traditional side eaves, the lateral occupied width is reduced from 18mm (conventional 64P connectors) to 15.3mm, achieving 15% space savings. This makes it suitable for compact layout scenarios such as 1U servers and industrial embedded motherboards.Enhanced EMI Compatibility: It reduces signal reflection caused by metal obstruction, and compresses the safety distance between the EMI shield and surrounding components from 2mm to 1mm, meeting the layout requirements of high-density PCBs.

◆◆ Product Advantage

1. High-Speed Transmission Performance: Bandwidth Leap for x4 LanesCompared with PCIe 4.0 64P connectors, the bandwidth has increased from 8GB/s to 16GB/s.

2. Equalization Technology AdaptationIt integrates a +8dB pre-emphasis circuit at the transmitter and a multi-level CTLE/DFE (Continuous-Time Linear Equalizer/Decision Feedback Equalizer) at the receiver. Through a 3-tap DFE, it compensates for 36dB of channel loss, enabling distortion-free signal transmission in the 16GHz frequency band.

3. Adaptation for High-Density DeploymentThe design without side eaves reduces the PCB area occupied by a single connector by 22%. Combined with two mounting options (vertical/right-angle), 2-3 connectors can be integrated on a 10cm×15cm embedded motherboard, meeting the expansion needs of multiple devices.

4. Adaptation for Extreme EnvironmentsThe side slots accelerate heat dissipation, and when combined with the low thermal conductivity of the LCP (Liquid Crystal Polymer) housing, it maintains stable contact resistance (≤50mΩ) even in an industrial environment of +125℃.

5. High Reliability and Durability

• Mechanical Stability: It uses phosphor bronze pins (with a gold plating thickness of 150-250 microinches), achieving an insertion/extraction lifespan of over 1000 cycles. It has passed the IPC-A-610 Class 3 soldering certification, and the pin extraction force is controlled between 0.5-2.5N, balancing reliability and operational convenience.

• EMI Shielding Capability: The metal shield housing and PCB ground plane form 360° electromagnetic shielding, meeting the CISPR 32 Class B standard. The signal bit error rate is less than 10⁻¹² in industrial high-interference environments.

6. Full Compatibility and Cost Advantage

• Its physical interface is fully consistent with that of PCIe 4.0/3.0 64P connectors, supporting automatic speed negotiation (5GT/s~32GT/s). PCIe 4.0 NVMe SSDs can operate stably at 16GT/s when inserted.

• It is compatible with testing tools from major manufacturers such as TE and Samtec, as well as simulation models (IBIS-AMI), reducing design verification costs by 30%.
