全球首款4×112G 算力中心模拟CDR电芯片由上海米硅突破!
半导体芯闻· 2025-12-23 10:35
如果您希望可以时常见面,欢迎标星收藏哦~ 以前跟随为主,现在慢慢走到无人区,可参考的地方越来越少了。米硅已全面着手研发4*224G ASP(CDR)系列产品,4*448G ASP 系列已在蓝图。一边定义下一代产品,一边把技术边界再往前 推,前面没有参照物,就自己成为坐标。 关于米硅科技 技术原理对比: CDR(时钟数据恢复)通过模拟电路提取时钟信号,主要解决抖动问题。核心组件包括鉴相器、锁相 环(PLL)和频率检测器,像传统相机的光学防抖,用物理方式稳定信号。 ODSP(光学数字信号处理)采用ADC将模拟信号数字化,通过数学算法补偿光纤损耗、色散和非线 性效应 >。相当于用Photoshop的AI算法逐像素修复,能处理PAM4/相干调制等复杂信号。 算力中心短距连接 米硅科技的4x112G PAM4 CDR核心技术除了400G、800G光模块可替代oDSP方案打破海外垄断 同时成本功耗降50%-70%, 同时也可用于400G、800G AEC方案,在3-7米铜缆传输场景替代传统 DSP方案,成本功耗可降低50-70% 新的挑战,新的规划 米硅科技首款自研4X112G ASP(CDR)电芯片收发套片ms8904 ...
【UNFX财经事件】假期前市场缺乏共识 各类资产维持区间运行
Sou Hu Cai Jing· 2025-12-23 10:19
政策层面,美联储内部对后续路径的分歧持续影响市场定价。美联储理事斯蒂芬·米兰指出,若政策环 境无法继续放松,经济下行风险可能上升,该表态进一步强化了市场对未来宽松空间的定价。在此背景 下,美元指数在GDP数据公布前维持弱势整理,整体技术结构仍偏承压。与此同时,市场亦关注GDP价 格指数等通胀分项数据,其变化将直接影响美联储对增长与通胀平衡的判断。在假期流动性不足的环境 中,美元对单一数据的短线敏感度有所放大。 外汇市场中,日元表现相对突出。周二亚欧时段,日元连续第二个交易日走强,美元/日元在156.00关 口附近持续承压。日本财务大臣片山五月及外汇事务官员接连释放偏强立场,强化了市场对官方干预的 预期。与此同时,日本央行并未排除进一步加息的可能性。在上周将政策利率上调至三十年来高位后, 日本10年期国债收益率升至26年新高,与市场普遍预期美联储在2026年继续降息形成鲜明对照。政策分 化叠加地缘政治不确定性,使日元在年末阶段获得持续支撑。 从交易层面看,当前市场正处于假期效应与宏观数据窗口交汇阶段。股指期货整体波动受限,趋势性机 会有限,更适合以区间交易与事件驱动为主;外汇市场中,美元整体偏弱,但在关键数据公 ...
