5 / 10 page  Parameter Measurement Information (Continued) Application Information SKEW Skew may be thought of in a lot of different ways, the next few paragraphs should clarify what is represented by t SK in this datasheet and how it is determined. Skew, as used in this databook, is the absolute value of a mathematical differ- ence between two propagation delays. This is commonly accepted throughout the semiconductor industry. However, there is no standardized method of measuring propagation delay, from which skew is calculated, of differential line re- ceivers. Elucidating, the voltage level, at which propagation delays are measured, on both input and output waveforms are not always consistant. Therefore, skew calculated in this datasheet, may not be calculated the same as skew defined in another. This is important to remember whenever making a skew comparison. Skew may be calculated for the DS89C386, from many different propagation delay measurements. They may be classified into two categories, single-ended and differential. Single-ended skew is calculated from t PHL and tPLH propa- 01208505 CL Includes load and test jig capacitance. S1=VCC for tPZL, and tPLZ measurements. S1 = GND for tPZH, and tPHZ measurements. S1 = Open for tPLH,tPHL, and tSK. FIGURE 2. Test Circuit for Switching Characteristics 01208506 FIGURE 3.
