1. **会议主题**:2025年1月28-30日圣克拉拉会议中心,聚焦200Gbps/lane(106/112 GBd/lane)高速串行数据测量带宽与均衡方法。 2. **核心问题**:测量带宽(如67GHz)与滤波器滚降特性对COM(通道操作裕度)结果的影响,可能导致误判DUT合格性。 3. **实验数据**: - 实际DUT信号(106.25 GBd)在70GHz带宽限制下,COM结果(约0.646dB)对后续滤波器(Bessel/Butterworth)不敏感。 - 仿真显示,67GHz以上频率能量对COM影响显著(可达0.8dB),需85GHz带宽减少误判。 4. **结论**:标准需统一测量带宽规范,建议使用85GHz设备以降低“误失败”风险。
**带宽如何影响测量?** **COM测试有何新发现?** **67GHz够用吗?**
