Shielded cable
First Claim
1. A shielded cable comprising:
- first signal wires for transmitting digital signals of a relatively high frequency;
second signal wires for transmitting digital signals of a relatively low frequency; and
a conductor with which said first and second signal wires bundled in a state of being electrically insulated from each other are collectively covered, wherein said first signal wires are placed adjacent to said conductor and adjacent one to another.

Abstract
In placement of a plurality of signal wires in a shielded cable, a plurality of signal wires for transmitting digital signals of a relatively high frequency are placed adjacent to an outer shield with which the shielded cable is covered, and also adjacent one to another. The degree of capacitive coupling maximized with respect to high-frequency signal wires is thereby maintained with stability, thus enabling impedance control. Also, a skew at the connection between the shielded cable and a connector can be reduced. Thus, a shielded cable is provided in which impedance control and skew control are easily and stably performed without using cost-increasing means such as addition of ground and power supply wires to improve signal quality.
