实时眼图分析已经成为SerDes系统设计和调试中的核心工具，通过信号准备、时钟数据恢复、掩模测试、串行模式触发和电缆损耗去嵌入等五个步骤，工程师可以有效评估和优化高速信号传输中的问题，提升SerDes接口的可靠性和性能。

What is a Serdes Eye Diagram? A Serdes (Serializer/Deserializer) eye diagram is a graphical representation of signal integrity in high-speed digital communication systems. It allows engineers to analyze and troubleshoot the quality of signal transmission by examining the eye pattern of …

A SerDes channel typically is a differential signal transmission channel. A hardware SerDes channel is typically characterized by measuring its N-port S-parameters and is typically a 4-port. The 4-port differential input ports are typically port 1 (+) and port 3 (-).

2022年8月12日 · 眼图是将数据信号在相同单位时长内把码流叠加到一起形成的图形，可直观地评估信号性能指标。 眼图是时域角度的统计结果，在横轴为时间、纵轴为电压幅值的二维平面内，眼图在时间轴上的时间差表现为眼宽，在纵轴上的电压幅值表现为眼高。 评估眼图一般看眼高和眼宽。 眼图的张开程度能表明信号的好坏，抖动越小眼宽越宽，噪声越小眼高越高。 通常，眼图能够清楚地体现出信号抖动、噪声和周期。 眼图模板 (EYE MASK)，它形象地反映了协议规定的 …

2018年3月20日 · SerDes standards typically use eye diagram characterizations to measure amplitude, de-emphasis, jitter, skew, common mode voltage, signal-to-noise ratio (SNR), and rise and fall times. The vertical eye opening, usually called eye height (EH), is measured at the sampling point which, in most cases, is a 0.5UI +/- tolerance.

2008年11月24日 · Maxim用于LVDS信号链路的串行器和解串器(SerDes)非常适合汽车和电信系统的视频显示、图像采集以及数据传输系统。 当使用SerDes芯片组传输高速数据时，设计人员需要了解SerDes链路的性能，以便确定数据传输的可靠性裕量。

2008年7月22日 · This application note presents an experimental approach for generating the eye template of a SerDes chipset. The new approach decouples the signal swing from jitter tolerance by determining the threshold over which the signal …

Use this tool to analyze a SerDes system with a single differential channel for the channel impulse and frequency domain characteristics, and the system for its eye diagram, BER response and more. Include NRZ or PAM4 source, transmitter model, channel impulse response or 4-port S-parameters, receiver front end model and receiver CDR/DFE model.

2025年1月1日 · 实时眼图分析已经成为SerDes系统设计和调试中的核心工具，通过信号准备、时钟数据恢复、掩模测试、串行模式触发和电缆损耗去嵌入等五个步骤，工程师可以有效评估和优化高速信号传输中的问题，提升SerDes接口的可靠性和性能。
