switching time. A shorter rise time corresponds to a faster slew rate and faster possible bit rates. In general, the time required to transmit a bit should be 5—10 times longer than the rise time to ensure that the voltage has reached a valid logic level by the time the receiver reads the bit. For example, an RS-485 driver rated for use at 2.5 MHz might have a maximum rise time of 0.06 ps, which is 15% of the bit width. The bit rate is also important because transmission-line effects such as ringing and reflected voltages occur during and immediately after voltage transitions, while receivers read logic levels near the middle of the bits. At slower bit rates, the bits are wider, and the voltages are likely to have settled by the time the receiver detects them. To understand why rise and fall times are a measure of frequency, consider the most basic digital signal, a square wave, which has alternating, equal-width high and low voltages. Mathematically, a square wave is the sum of a sine wave of a fundamental frequency and its odd harmonics. For example, a 100-Hz square 107 Chapter 7 SQUARE WAVE SINE WAVES Figure 7-2: A square wave is the sum of a sine wave and its odd harmonics. wave is the sum of a 100-Hz fundamental plus harmonics of 300, 500, 700 Hz and so on up. Figure 7-2 illustrates. A square wave containing an infinite number of harmonics has instant transitions and rise and fall times of zero. In real life, the laws of physics limit the high frequencies and result in rise and fall times greater than zero. A signal that contains few harmonics has gradual transitions and long rise and fall times. As the number of harmonics increases, the edges sharpen and the rise and fall times shorten. Serial data is more complex than a square wave, but the basic principle is the same: the higher the frequencies that make up the signal, the sharper the transitions. Cable Delay Another concept related to understanding long and short lines is cable delay. One-way delay is the t prom-electric.ru
