Abstract
A data processing circuit has four signal conductors between a driver and a receiver, and first and second, mutually conducting shield planes. First and second signal conductors form a symmetrical stack in a column between the first and the second plane. Third and fourth signal conductors are arranged substantially midway between the first and the second plane, on mutually opposite sides of the stack. The first, second, third and fourth signal conductors have respective widths so that respective transmission line impedances of transmission lines between each particular one of the first, second, third and fourth conductors and the first and second planes are substantially mutually equal.
Claims4
A data processing circuit, comprising:
- a driver with four signal outputs;
- a receiver with four inputs;
- a first, second, third an fourth signal conductor, each connected between a respective one of the inputs and outputs;
- first and second mutually coupled conducting shield planes, the first and second signal conductors forming a symmetrical stack in a column between the first and the second plane, the third and fourth signal conductors being arranged substantially midway between the first and the second plane, on mutually opposite sides of the stack, the first, second, third and fourth signal conductors having respective widths so that respective transmission line impedances of transmission lines between each particular one of the first, second, third an fourth signal conductors and the first and second planes are substantially mutually equal.
