Embodiment Construction

[0029] One aspect of the present invention will be described below with reference to the accompanying drawings.

[0030] FIG. 1 shows a configuration for a fast signal interface portion of a computer system according to one aspect of the present invention. The computer system is a notebook type personal computer (PC) in which the serial transfer controller 101 is implemented on a printed circuit board (PCB) 100a mounted on a notebook computer body 100 as a system board.

[0031] The serial transmission controller 101 transmits a plurality of fast serial signals to an external unit through the connector 102 and receives a plurality of fast serial signals from the external unit through the connector 102 . The external unit is, for example, a docking station connected to the notebook computer body 100 through a cable when needed in order to expand the functions of the notebook computer body 100 . By connecting the connector 110 on the cable to the connector 102 of the notebook b...

Abstract

To realize a high speed serial interface by way of a connector by making it possible to maximally suppress a skew between signals. C1, C2 and C3 are terminals of a connector type #1 in which they are arranged on an upper row and D1, D2 and D3 are terminals of a connector type #2 in which they are arranged on a lower row. Signal wiring 103, 104 and 105 corresponding to signals A1, A2 and A3 respectively are connected to the connector terminals C1, C2 and C3 of the connector type #1.

Description

technical field [0001] The present invention relates to electronic equipment and computer systems with fast serial interfaces. Background technique [0002] Various notebook-type personal computers (hereinafter referred to as "notebook computers") have been developed because they operate on batteries and are easy to carry. Some laptops are configured to fit within an expansion unit for extended functionality. In order for the notebook computer body to effectively utilize the resources of the expansion unit, it is important to connect the bus of the notebook computer body to the bus of the expansion unit. This bus connection allows devices on the Expansion Unit bus to have the same control as devices on the notebook's main bus. [0003] Many personal computers use a PCI (Peripheral Component Interconnect) bus. Therefore, the notebook computer body and the expansion unit are usually connected by the bus using the docking connector provided for the notebook computer body and...
