JEEE 1394 works as follows: (1) IEEE 1394 bus topology. IEEE 1394 serial bus topology can be divided into two environments: the environment and 35 datasheet and the bottom cable environment. Bus connections between different environments require bus bridge. Cable environment, the physical topology is acyclic network structure, each node connected by a cable between the port, the branch was extended to form a tree or daisy-like network topology. Floor environment, the physical topology is more access (Multidrop) bus. Bus on the distribution of more than one connector, allowing direct insertion node, through arbitration so that all nodes access the bus. (2) IEEE 1394 physical interface. IEEE 1394 devices via a standard six-conductor cable to transmit signals, as shown in Figure 14-5. The TPA TPA and 35 price and TPB ...

This resistor has two effects: first impedance matching. Because the signal source impedance is very low, with the impedance mismatch between the signal line, in series with a resistor, can improve the match, so as to reduce reflection, to avoid oscillation and 35 datasheet and so on. Second, it could reduce the extent of the steep edge of the signal, thus reducing high frequency noise and 35 price and overshoot, etc. Because the series resistance, capacitance and 35 suppliers and signal distribution line and load input capacitance form an RC circuit, which would reduce the steepness of the signal edges. If a signal edge is very steep, with a large number of high-frequency components, will be radiated interference, the other, it tends to overshoot. Typically, high-speed signal lines before considering the use of such resistance. At...
