frequencies in the signals carried by the wires, and how fast the signals travel in the wires. When the wires are physically short and the frequencies are low, the time required for signals to propagate down the wires has little effect on signal quality. The circuit is considered a lumped system, and the wires form a short line. In many respects, you can think of short lines as perfect, zero-impedance conductors. When an output switches state, you can assume that the input at the other end of the cable instantly sees an identical voltage. When the wires are physically long and the frequencies are high, the time required for a signal to propagate down the wires is significant. This type of circuit is considered a distributed system, and the wires form a long line. Another name for a long line is transmission line. On a long line, terminating components can help ensure that the receiver sees a clean signal by reducing reflected voltages on the line. Understanding how long and short lines behave requires understanding the effects of two parameters: rise time and cable delay. 106 Designing RS-485 Links and Networks RISE TIME FALL TIME Figure 7-1: A circuit with short rise and fall times contains high frequencies, even if the bit rate is slow.. Rise Time Rise time is the time required for an output to switch from 10% to 90% of full range Figure 7-1 . Fall time is the time required for an output to switch from 90% to 10% of full range. The rise and fall times are often equal or nearly equal, so some sources use rise time to refer to transition time in general. The rise time of a digital signal is an indication of the frequencies that make up the signal. A faster rise time means the signal contains higher frequencies. The data sheets for RS-485 drivers specify typical and maximum rise and fall times. The values range from a few nanoseconds to nearly a microsecond. The specifications assume a defined load, often 54Q and 50 or 100 pF, with higher capacitance resulting in a prom-electric.ru
