Abstract

A connector receptacle (20) is constituted by a contact (2) to which a data signal is serially communicated through a connector plug and a physical layer basic circuit (5) provided inside the connector receptacle (20) and adapted to perform specified processings so that the data signal is parallel communicated between the basic circuit and a link layer circuit for the communication. As a result, the distance between the contact (2) and the physical layer basic circuit (5) is short. Therefore, it is not necessary to pay so much attention as in conventional cases in designing a pattern layout (7) so as to prevent influence on the EMI and transmission characteristics, and it is easy to design the layout of the pattern constituting the transmission line for the data.

Claims

1. A connector receptacle comprising:

a housing having at least one mating portion configured to mate with a connector plug; and

a plurality of contacts positioned to be electrically connected to the connector plug when the connector plug is mated with the mating portion; and

a physical layer basic circuit provided on the housing and configured to perform predetermined operations such that a data signal is communicated in series with the contacts through the connector plug and in parallel with a link layer circuit for communication.

2. A connector receptacle according to claim 1, further comprising a plurality of transmission lines each having substantially constant characteristic impedance and configured to communicate said data signal in series from said contacts to said physical layer basic circuit.

3. A connector receptacle according to claim 1, further comprising a plurality of transmission lines each having substantially same length and configured to transmit said data signal between each of said plurality of contacts and said physical layer basic circuit.

4. A connector receptacle according to claim 1, wherein said physical layer basic circuit is provided on a substrate and said contacts are positioned on a substantially same plane as the substrate.

5. A connector receptacle according to claim 1, wherein said at least one mating portion comprises a plurality of mating portions.

6. A connector receptacle according to claim 5, wherein said physical layer basic circuit performs said predetermined operations so that a data signal is communicated in series with said connector plugs mate with said plurality of mating portions and communicated in parallel with said link layer circuit.

7. A connector receptacle according to claim 1, further comprising a plurality of transmission lines through which the data signal is transmitted from said connector plug and a shielding member shielding the plurality of transmission lines from the outside.

8. A connector receptacle according to claim 1, wherein said physical layer basic circuit is provided on an MID substrate and said contacts are held by the MID substrate.

9. A connector receptacle according to claim 1, further comprising a plurality of transmission lines formed on the housing, wherein said data signal is transmitted in parallel through the plurality of transmission lines which are N times as many compared with the plurality of transmission lines for communication in series, and a rise time and fall time when said data signal is communicated in parallel is N times as long compared with the rise time and fall time when said data signal is communicated in series.

10. A connector receptacle according to claim 1, wherein said physical layer basic circuit comprises a connector input-output control circuit, a physical layer control circuit, an encoding circuit, a decoding circuit, and an input-output interface circuit.
