  • High-Speed Connectors: Powering AI, 5G, and Next-Gen Data Demands

    Technology never stops evolving. Some innovations emerge before the market is even ready, like the first tablet computers, which arrived before touchscreens became mainstream. Others are born out of necessity. USB Type-C, for example, simplified the confusing world of charging and data cables.

    Today, the interconnect industry faces a similar turning point. The explosive growth of 5G networks, the Internet of Things (IoT), and artificial intelligence (AI) has created unprecedented demand for faster, more reliable data transmission. To keep up, engineers are exploring new signaling methods and connector designs that balance speed, efficiency, and signal integrity.

    From NRZ to PAM4: A Smarter Way to Send Data

    Traditional communication systems rely on non-return-to-zero (NRZ) signaling, which transmits data using two voltage levels. Each transition represents a single bit simple and effective, but limited.

    Now, enter Pulse Amplitude Modulation 4-level (PAM4). Instead of two voltage levels, PAM4 uses four, doubling the data capacity without raising the transmission frequency. By transmitting two bits per cycle, PAM4 enables faster throughput while keeping systems efficient.

    However, this leap in performance comes with challenges. The smaller “eyes” in PAM4 eye diagrams mean signals are more vulnerable to noise, crosstalk, and electromagnetic interference. As speeds climb, even tiny distortions or timing issues, known as jitter, can lead to millions of errors per second. That’s why maintaining signal integrity has become a top engineering priority.

    The Role of Connectors in Preserving Signal Quality

    Every signal travels along a chain of transmitters, cables, and connectors, and each link affects overall performance. Depending on distance and application, different solutions are needed:

    • Long distances (rack-to-rack or data hall): Optical fiber is best due to its low attenuation and immunity to EMI. Though more costly, fiber ensures strong signal integrity across extended runs.
    • Medium distances (top-of-rack to middle-of-row): Active copper cables are often used. These contain built-in electronics to preserve signals but require extra power and cooling.
    • Short distances (within boards or chassis): Passive copper solutions shine here, offering compact and energy-efficient connections. However, only advanced connectors can handle the extreme data rates demanded by AI and cloud workloads.

    Molex Mirror Mezz: A Next-Generation Connector

    For today’s high-performance computing and data center needs, Molex Mirror Mezz connectors stand out.

    • High Density: With up to 115 differential pairs per square inch, they maximize space while leaving room for other critical components.
    • Superior Performance: Designed for 56Gbps NRZ and 112Gbps PAM4, they deliver excellent signal integrity.
    • Reduced Complexity: A hermaphroditic, self-mating design cuts down on part count and simplifies the bill of materials.
    • Flexibility: Compatible with flex cables, these connectors extend distances without sacrificing performance.

    The Mirror Mezz Pro takes it further, supporting 112Gbps PAM4 for mainstream AI and cloud applications. Its low insertion loss and minimal crosstalk make it ideal for high-density, high-speed environments.

    Conclusion: Balancing Speed, Power, and Reliability

    Designing systems for AI, 5G, and next-gen data centers means solving a puzzle: how to achieve faster data rates while minimizing interference, loss, and energy use. PAM4 signaling provides the foundation, but advanced connectors like Molex Mirror Mezz ensure those signals remain clear and reliable.

    As workloads continue to grow, these innovations aren’t just keeping pace, they’re shaping the future of high-speed communication.

  • 3D Metal Printing: Transforming the Future of Medical Implants

    Implantable medical devices (IMDs), from stents to hip replacements, are critical for restoring health and mobility. Traditionally, patients often had to rely on off-the-shelf implants, which don’t always provide the best fit. In other cases, customized IMDs took longer to produce, delaying treatment and prolonging discomfort.

    Today, 3D metal printing is reshaping this process. It offers faster production, greater customization, and better biocompatibility, giving healthcare providers and patients more reliable solutions.

    Why 3D Metal Printing is a Game-Changer

    Unlike conventional methods, 3D printing brings design freedom and supports advanced materials that are difficult to process otherwise. For IMDs, this means implants can be created with:

    • Perfect fit and geometry tailored to the patient
    • Biocompatible surfaces that integrate naturally with tissue (osseointegration)
    • Robust strength to resist biofluids and long-term wear

    Compared to plastics or ceramics, metal alloys remain superior for IMDs. Since many implants are already made from metals, 3D printing extends and improves upon existing practices with more flexibility and efficiency.

    The Power of Customization in IMDs

    Customization is crucial. Poorly fitted implants can cause pain, limit movement, and even require replacement surgeries. With 3D-printed implants, medical professionals can design devices with the exact shape, size, and surface finish needed for each patient.

    Common implants now benefiting from 3D printing include:

    • Acetabular (hip) cups
    • Knee and shoulder implants
    • Spinal cages and bone plates
    • Stents
    • Foot and ankle implants

    This flexibility reduces the risk of follow-up surgeries while improving patient comfort and recovery times.

    Speed and Efficiency Advantages

    Another major benefit of 3D metal printing is speed. Traditional manufacturing often requires additional steps like polishing or hot isostatic pressing (HIP). By contrast, 3D printing can produce finished implants faster, without multiple rounds of post-processing.

    Furthermore, healthcare providers can install 3D printers directly in medical facilities, enabling real-time collaboration between clinicians and engineers. This capability speeds up implant design, reduces wait times, and allows quicker patient care.

    Expanding Material Possibilities

    Beyond speed and customization, 3D printing unlocks new material opportunities. It can work with alloys that are otherwise difficult to process, such as:

    • Titanium alloy (Ti-64): Strong, lightweight, and biocompatible
    • Cobalt chrome: Highly durable and corrosion-resistant
    • Stainless steel: Affordable and versatile

    With careful design, scientists can alter porosity, microstructure, and surface finish at the microscopic level. This allows implants to be made either more rigid for strength or more sponge-like for flexibility, depending on their application. For example, spinal cages may be designed to expand with natural breathing movements while still maintaining stability.

    Conclusion: A Healthier Future with 3D Printing

    3D metal printing is revolutionizing implantable medical devices by combining speed, strength, and personalization. Patients benefit from implants that fit better, last longer, and integrate more naturally with the body. Healthcare providers also gain faster production times and more reliable outcomes, reducing the need for costly and invasive follow-up procedures.

    As the technology advances, 3D-printed IMDs will continue to redefine what’s possible in modern medicine—offering patients safer, stronger, and more tailored treatments.

  • 48V Power in Data Centers: Efficiency and Reliability with BarKlip®

    Data centers are the engines of our digital world. From running AI algorithms to powering global cloud storage, they work around the clock like cities that never sleep. But with every leap in computing power, their hunger for energy grows.

    Traditionally, server farms relied on 12VDC power distribution. For many years, this system did the job. However, as workloads expanded, 12V solutions started to fall behind. They became inefficient, costly, and harder to scale.

    That’s why a new standard is taking over: 48VDC power distribution. This upgrade offers higher efficiency, lower costs, and a path toward more sustainable computing. Let’s explore why data centers are making the switch—and how Amphenol’s BarKlip® connectors help them get there.

    Why Move from 12V to 48V?

    As computing workloads intensify, power delivery becomes a bottleneck. For example, a 12V rack can stay fairly efficient (around 80%) up to 15kW. But once it crosses that threshold, efficiency drops sharply—sliding down to 64% at 36kW.

    In contrast, 48V systems hold efficiency close to 90%, even for racks requiring more than 15kW. This difference is game-changing. Here’s why:

    • Reduced power loss: Higher voltage means less current, which means less wasted energy.
    • Cooler operation: With lower current, there’s less heat to manage, reducing cooling costs.
    • Smaller cables: 48V cables are almost 90% thinner than 12V cables, saving space and materials.
    • Higher rack density: By freeing space, data centers can fit more servers into the same footprint.
    • Lower costs over time: Less copper, smaller cooling systems, and better efficiency mean savings.

    Put simply: 48V delivers more computing power with less waste.

    Solving the Efficiency Puzzle with BarKlip® Connectors

    Transitioning to 48V is about more than voltage—it’s about reliability. Power shelves in server racks use busbars to distribute electricity, and the connection points between busbars, cables, and circuit boards are critical. Weak or inefficient connections can create resistance, heat, and performance issues.

    This is where Amphenol’s BarKlip® Power Cable Assemblies step in. Specifically designed for the Open Compute Project’s (OCP) Open Rack v3 (ORv3), these connectors deliver maximum efficiency and reliability in high-density environments.

    Key benefits of BarKlip® connectors include:

    • Ultra-low resistance: Just 0.05mΩ end-of-life contact resistance, ensuring performance stays strong over time.
    • High current-carrying capability: Ready for demanding, power-dense applications.
    • Customizable design: Adaptable for power shelves, BBUs, server/storage sleds, and more.
    • Durability and safety: High-conductivity copper alloy with ultrasonic welding and extra grounding.

    By reducing losses at the most critical points, BarKlip® connectors improve overall system performance and extend hardware lifespan—all while cutting long-term costs.

    The Bigger Picture: Why 48V Is the Future

    Yes, moving from 12V to 48V may require retrofitting racks and upgrading hardware. Yet, the payoff is well worth it. Data centers that adopt 48V gain:

    • Higher computing density → More power, less space.
    • Improved efficiency → Less energy wasted, fewer cooling requirements.
    • Environmental benefits → Lower energy use means a smaller carbon footprint.
    • Future-proof systems → Ready to support AI, IoT, and next-gen workloads.

    The global demand for faster, smarter, and greener computing isn’t slowing down. And in that future, 48V power distribution will be the gold standard. With Amphenol’s BarKlip® connectors, data centers can embrace this shift confidently—unlocking efficiency, reliability, and sustainability all at once.

    • Track stolen bikes via GPS
    • Customize ride profiles through mobile apps

    These features not only improve convenience but also open the door for manufacturers to offer subscription services, remote diagnostics, and personalized riding experiences.

    Powering the Next Generation of E-Bike Technology

    Meeting the demands of smart e-bike systems requires equally advanced microcontrollers. For example, NXP Semiconductors’ S32K37 and S32K39 microcontrollers are designed for motor control and BMS applications.

    Key features include:

    • Dual split-lock Arm® Cortex®-M7 cores and one lockstep core pair running at 320MHz
    • Motor control coprocessors with high-resolution PWM (in the S32K39 variant)
    • A built-in CoolFlux DSP for audio and signal processing
    • Up to 69 external analog inputs for monitoring battery voltages and temperatures

    With these capabilities, developers can create e-bike systems that are smarter, safer, and more efficient than ever before.

    The Road Ahead: Smarter, Not Just Faster

    The future of e-bikes isn’t just about speed or bigger batteries. It’s about intelligence, adaptability, and connectivity. By combining torque sensors, advanced BMSs, and IoT-powered ride ecosystems, the next generation of e-bikes promises:

    • Longer-lasting batteries
    • Safer and more reliable rides
    • Personalized and connected cycling experiences

    In short, e-bikes are becoming smarter companions on the road, redefining what it means to ride. Whether you’re a commuter, an adventurer, or a casual cyclist, the e-bike revolution is bringing a new level of performance and enjoyment to every journey.

  • From Analog Signals to Digital Audio: How Sound Becomes Data

    Turning natural sound into precise digital data lies at the heart of today’s audio technology. This process, known as analog-to-digital conversion (ADC), ensures that every note, voice, or sound effect is captured accurately while taking advantage of the durability and flexibility that digital formats offer.

    From microphones to studio mixing desks, every step of this transformation depends on carefully engineered systems that preserve the authenticity of sound while making it easier to process, store, and share.

    What Are Analog Signals?

    To understand digital audio, it helps to first know what analog signals are. Essentially, they are continuous waveforms, like the vibrations produced by a guitar string or a singer’s voice captured by a microphone. These waveforms carry a tremendous amount of detail, which is why analog recordings can sound so rich and natural.


    However, analog signals also have limitations:

    • Noise and distortion
    • Signal degradation over time
    • Storage and reproduction limits

    Because of these weaknesses, digital formats were developed. Digital audio not only preserves sound quality but also enables advanced features like compression, streaming, and precise editing.

    How Analog-to-Digital Conversion Works

    The conversion from analog to digital happens in several carefully controlled stages. Each stage ensures that the original sound is faithfully represented in a digital format.

    1. Sampling

    The analog waveform is measured at fixed intervals. Common sampling rates include:

    • 44.1 kHz (used in CDs)
    • 96 kHz (used in professional studio recordings)

    Higher sampling rates capture more detail, improving fidelity.

    2. Quantization

    Next comes quantization. Here, each sampled point is assigned a numerical value, forming the digital representation of the sound. This step allows computers, processors, and storage devices to work with the audio efficiently.

    3. Signal Processing (DSP)

    Once digitized, audio passes through digital signal processing (DSP). DSP techniques include:

    • Noise reduction
    • Equalization
    • Filtering and effects

    DSP is also what powers modern features like active noise cancellation (ANC) in headphones, adaptive EQ, and immersive spatial audio.

    4. Digital-to-Analog Conversion (DAC)

    Finally, to hear the sound, digital audio must be converted back into analog form. DACs perform this task, turning numbers into continuous waveforms that drive speakers or headphones. Advances in high-resolution DACs and planar magnetic drivers are helping audio reproduction reach unprecedented levels of clarity.

    DSPs: The Power Behind Modern Audio

    DSPs (Digital Signal Processors) enable real-time control of audio. They allow manufacturers and sound engineers to:

    • Tailor audio to different environments
    • Experiment with effects and spatial sound
    • Enhance dynamic range

    From studio mastering to everyday earbuds, DSPs are central to modern listening experiences.

    Cutting-Edge Audio Components

    Two innovative products highlight how far audio amplification and signal processing have come:

      • Available with the MAX98380EVSYS evaluation kit for real-world testing

    These components show how semiconductor technology continues to shape high-fidelity, energy-efficient audio systems.

    From Sound to Data: Technology Meets Artistry

    The journey from analog sound to digital audio is more than just technical—it’s a blend of artistry and science. Each stage, from sampling to playback, ensures that the final sound is as true to the original as possible while benefiting from the precision of digital systems.

    Whether you’re an audiophile, a sound engineer, or simply a music lover, understanding this process reveals how creativity and technology come together to create immersive, high-quality listening experiences.
