The electrical specifications for PCIe (Peripheral Component Interconnect Express) are critical to ensuring high-speed data transfer, signal integrity, and compatibility across devices. Below is an overview of the key electrical parameters for PCIe across various generations. PCIe Electrical Specifications 1. Voltage Levels PCIe Standard Voltage: 3.3 V for signaling (control logic), with 12 V for auxiliary power in some configurations. I/O Signaling: Differential Pair Signaling: PCIe uses Low Voltage Differential Signaling (LVDS) with typical voltages around 0.8 Vpp (peak-to-peak) for each lane. 2. Differential Pair Characteristics Differential Signaling: PCIe lanes consist of pairs of signals (e.g., TX+/TX-, RX+/RX-). Data is transmitted as the voltage difference between the positive (P) and negative (N) lines, reducing noise and crosstalk. Impedance: 85 Ω ± 15% (differential impedance) on the transmission line. #Capacitor #Electronics #PassiveComponents #Capacitance #ElectricalEngineering #Resistor #PassiveComponents #Resistance #Inductor #Inductance #ElectronicsDesign #CircuitDesign #PCBDesign #HardwareDesign #PCB #PCBLayout #CircuitLayout #ElectronicsLayout #ElectricalEngineering #EmbeddedSystems #TechDesign #Engineering #Engineering #Electronics #HardwareDesign #PCBDesign #EmbeddedSystems #IoT #CircuitDesign #PowerElectronics #DCDCConverter #SignalIntegrity #HighSpeedDesign #AnalogDesign #DigitalDesign #OrCAD #Cadence #AltiumDesigner #KiCAD #Ethernet #PCIE #DDR #I2C #UART #SPI #Tech #Innovation #STEM #CareerGrowth #ProfessionalDevelopment

Qualcomm's new forecasts after Investor Day met with a lack of the enthusiasm from the market https://lnkd.in/gztNti_y Qualcomm owned the smartphone market and that showed in the valuations however as per this report "Qualcomm plans to significantly move beyond the smartphone segment and aims for 50% of its business exposure to be in segments other than smartphones by 2030" which may sound exciting to some, but given how dominant Qualcomm had been in smartphone market, the above move changed it from "a sure thing" to "selling into lots of uncertainty"

Numemory reinvents Optane storage-class #memory 💡 Chinese fabless #semiconductor startup Numemory is developing storage-class memory (SCM) #chips using Optane-like phase change memory and crossbar #technology. Numemory, a business unit of Xincun Technology (#Wuhan), has launched the NM101, a storage-class memory #chip with 10x faster read and write speeds and 5x longer endurance than #NAND #chips. Xincun Technology was established in July 2022 and has developed a 3D selector-only memory (SOM) #technology using phase-change memory and a crossbar structure, which is remarkably similar to Intel Corporation and Micron Technology’s failed Optane #memory technology. Numemory’s website states: “The new memory is a type of SCM (storage-class memory) that can increase #storage capacity, reduce costs, and thus greatly improve the overall performance of the storage system. The new memory is considered to be a next-generation non-volatile storage technology that is very promising for large-scale mass production, and has become a hot topic of international concern in recent years.” Thanks again to Chris Mellor and Blocks and Files for the full article with more background and insights via the link below 💡🙏👇 https://lnkd.in/emUECvnU #semiconductorindustry #semiconductormanufacturing #technology #ai #tech #innovation #dram #nand #nandflash #flashmemory #server #computer #datacenter #foundry #it #computing #computer #ic

U.S. Push for Domestic Chip Production https://lnkd.in/gDQunsde - Geopolitical Concerns: U.S. is pushing for domestic chip production due to the growing risk of geopolitical instability in Taiwan, where many U.S. tech companies currently source their chips. - Intel’s Struggles: Intel's foundry division has been underperforming, losing $1.6 billion, but remains a vital part of the Biden administration’s semiconductor strategy. - CHIPS Act: The U.S. government is investing heavily in the semiconductor industry, though funding disbursements to Intel may be delayed until operational improvements are made. - Tech Giants’ Flexibility: Companies like Nvidia have the capability to shift fabs if necessary, but doing so would impact performance and cost. The U.S. government, through Commerce Secretary Gina Raimondo, is encouraging major tech companies such as Nvidia and Apple to use Intel’s foundries for chip production, particularly AI chips, as part of a broader effort to reduce reliance on foreign manufacturers like Taiwan's TSMC. This push aligns with the Biden administration’s focus on bolstering U.S.-based semiconductor production, especially as geopolitical tensions around Taiwan continue to pose risks to the global supply chain.

TSMC's wafer pricing now $18,000 for a 3nm #wafer, increased over 3X in 10 years: Analyst 💡 At advanced nodes, #chips are not getting cheaper! Apple's A-series #smartphone processors have evolved significantly from the A7 (28nm) to the A18 Pro (3nm), gaining more cores, transistors, and features. With each new node, TSMC charged Apple more per wafer, so the price increased from $5,000 for a 28nm wafer with A7 processors to $18,000 for a 3nm-class wafer for A17 and A18-series processors, reports Ben Bajarin, the chief executive and principal analyst at Creative Strategies, Inc. Bajarin notes that as #Apple's A-series #chips have evolved, their #transistor count has consistently increased, starting at 1 billion in the #A7 and reaching 20 billion in the #A18 Pro. That makes sense because the number of cores and features has also increased: in 2013, the A7 featured two high-performance cores and a four-cluster #GPU, whereas, in 2024, the A18 Pro features two high-performance cores, four energy-efficient cores, a 16-core #NPU, and a six-cluster GPU.

Arm Is Rebuffed by #Intel After Inquiring About Buying Product Unit - Intel’s rapid decline has spurred takeover speculation - Arm is interested in product group, not factory operations Arm Holdings Plc approached Intel Corporation about potentially buying the ailing chipmaker’s product division, only to be told that the business isn’t for sale, according to a person with direct knowledge of the matter. In the high-level inquiry, Arm didn’t express interest in Intel’s #manufacturing operations, said the person, who asked not to be identified because the discussions were private. Intel has two main units: a product group that sells #chips for #personalcomputers, #servers and #networking equipment, and another that operates its factories. Combining with Intel would help Arm’s reach and kick-start a move toward selling more of its own products. The company currently licenses #technology and designs to customers, who then turn them into complete components. Its client list includes the biggest names in #technology, such as Amazon.com Inc., Qualcomm Inc. and Samsung Electronics Co.
