GMSL开源,SerDes生变
半导体行业观察· 2025-06-04 01:09
如果您希望可以时常见面,欢迎标星收藏哦~ 因为智能汽车的崛起,过去几年Serdes芯片市场关注度飞升。 根据盖世汽车研究院经分析预测,至2023年全球车载SerDes芯片市场规模就将达到数十亿美元, 未来十年,这一市场将朝着百亿美元规模高速发展。这其中,基于中国智能驾驶发展现况及潜力, 有望占四成。 然而在这巨大的机遇背后,SerDes芯片存在一些固有的格局。例如迄今,这个市场主要是由ADI 和TI两家模拟芯片供应商把持,他们分别利用GMSL和FPD-Link的先发优势统领了市场。由于这 两家厂商的协议都是私有的,这就让其他想插足这个市场的厂商各出奇招。 但随着GMSL官宣开源以后,SerDes市场一夜生变。 SerDes,双王争霸 如上所述,SerDes是一个双王争霸的市场。当中,FPD-Link(Flat Panel Display Link)是由美 国国家半导体公司(现隶属于德州仪器)于 1996 年创建的原始高速数字视频接口。FPD-Link 是 低压差分信号(LVDS) 标准的首个大规模应用。美国国家半导体公司立即为 FPD-Link 技术提供了 互 操 作 性 规 范 , 以 推 广 其 作 为 ...
共封装光学,达到临界点

Core Viewpoint - Co-packaged optics (CPO) technology is emerging as a promising solution to enhance bandwidth and energy efficiency in data centers, particularly for applications involving generative AI and large language models. However, manufacturing challenges remain, particularly in fiber-to-photonics integrated circuit (PIC) alignment, thermal management, and optical testing strategies [1][20]. Group 1: CPO Technology and Benefits - CPO enables network switches to route signals at speeds of terabits per second while significantly improving bandwidth and reducing power consumption required for AI model training [1][20]. - The technology achieves a bandwidth density of 1 Tbps/mm, optimizing rack space in increasingly crowded data centers [1][6]. - CPO can reduce power consumption associated with high-speed data transmission from approximately 15 pJ/bit to around 5 pJ/bit, with expectations to drop below 1 pJ/bit [6][7]. Group 2: Manufacturing Challenges - Key challenges in CPO manufacturing include achieving precise alignment between fiber and PIC, which is critical for effective optical signal coupling [8]. - The most common passive alignment method is the V-groove technique, which connects the fiber directly to the PIC to minimize loss [8][9]. - Efficient coupling between standard single-mode fibers and silicon waveguides is complicated due to significant differences in size and refractive index, leading to potential light loss [8][9]. Group 3: Thermal Management - CPO systems are sensitive to temperature fluctuations caused by high-power devices like GPUs and ASICs, which can affect the performance of photonic devices [11][12]. - A temperature change of just 1°C can lead to approximately 0.1nm wavelength shift in most photonic systems, necessitating careful thermal management strategies [11][12]. - Advanced thermal interface materials and monitoring circuits are deployed to maintain PIC temperature within predefined ranges [11][13]. Group 4: Reliability Design - Ensuring reliability in CPO systems is crucial, especially with multi-chip integration, requiring known good die (KGD) testing and optical testing solutions [14][16]. - High reliability designs incorporate redundancy, such as backup lasers, to maintain operation in case of component failure [15][16]. - Integrated monitoring and self-correcting features are being developed to detect performance degradation and facilitate quick recovery [15][16]. Group 5: Integration Techniques - Both 2.5D and 3D packaging methods are utilized in CPO, with 2.5D placing electronic ICs and PICs side by side on a silicon interposer [17][18]. - 3D integration allows for optimal manufacturing processes for each chip type, enhancing performance while increasing complexity and cost [18][19]. - The integration of optical features with traditional CMOS processes is becoming more compatible, facilitating advancements in CPO technology [17][18].

1.4nm,贵的吓人!
半导体行业观察· 2025-06-03 01:26
Core Viewpoint - Major technology companies like Apple, MediaTek, and Qualcomm are targeting TSMC's 2nm process, which has begun accepting orders at a cost of $30,000 per wafer, presenting a significant challenge for the next generation of process nodes. The subsequent 1.4nm "A" process is expected to be even more expensive, with costs potentially reaching $45,000 per wafer, a 50% increase compared to the 2nm node [1][3][12]. Summary by Sections 1.4nm Process Cost and Features - TSMC's A14 (1.4nm) manufacturing technology promises significant improvements in performance, power consumption, and transistor density compared to the N2 (2nm) process. The A14 process is expected to cost up to $45,000 per wafer, which is a 50% increase from the 2nm node [3][5]. - The A14 process will utilize TSMC's second-generation GAA (Gate-All-Around) nanosheet transistors and NanoFlex Pro technology, which allows for greater design flexibility. It is projected to achieve a 10-15% speed improvement, a 25-30% reduction in power consumption, and a logic density increase of approximately 1.23 times compared to the N2 process [5][7]. Potential Customers for 1.4nm Process - TSMC's top customers, including Nvidia, Apple, MediaTek, Intel, Qualcomm, and Broadcom, are likely to adopt the 1.4nm process. Nvidia is expected to significantly increase its contribution to TSMC's revenue, projected to rise from 5-10% in 2023 to over 20% by 2025 [8][9]. - Apple is anticipated to place orders worth approximately NT$1 trillion (around $33 billion) for 2nm technology by 2025, which could increase its share of TSMC's revenue significantly [9][10]. Future Cost Trends - The costs of wafers are expected to continue rising, with the 1.4nm process not utilizing expensive High NA EUV lithography technology, indicating potential for further price increases in future nodes [12][13]. - Analysis suggests that if the light source power does not increase, the overall lithography costs for future nodes could rise by up to 20% compared to the current 3nm baseline [14][16]. - The semiconductor industry is observing rising costs in EDA and IP, which may contribute to the overall increase in chip production costs in the future [17].
