Abstract
Printed circuit board having a termination of a T-shaped signal line having at least two line ends, one line end being terminated using a terminating resistor against a supply voltage, and the other line end being terminated against the reference potential of the supply voltage.
Claims8
A printed circuit board having a termination of a T-shaped signal line comprising:
- a first integrated circuit having at least one data output;
- a second integrated circuit and a third integrated circuit, each having a data input and a power supply unit for generating a supply voltage against a reference potential for the second and the third integrated circuits;
- a line beginning of the T-shaped signal line, connected to the data output of the first integrated circuit;
- at least two line ends of the T-shaped signal line, each connected to the data input of the second and the third integrated circuits;
- and
- first and second terminating resistors respectively terminating the line ends at the data inputs of the second and the third integrated circuits;
- wherein the first terminating resistor is terminated against the supply voltage, and wherein the second terminating resistor is terminated against the reference potential.
