Skew Margin Measurement for 4-Channel LVDS Serializers/Deserializers
Measuring receiver skew margin is a practical way to determine the jitter tolerance of multiple-input-channel LVDS deserializers like the MAX9209/MAX9222 parts. Although receiver skew margin has been defined and explained in the literature, no comprehensive measurement technique has yet been demonstrated. This application note shows a step-by-step method for measuring skew margin. Following this approach, you can clarify the specification and definition of skew margin in the data sheets for these 4-channel SerDes devices.
