Abstract

To provide a relay device capable of increasing the number of connected nodes in a bus-type network, and a connector providing the relay device. An ASC 1 as the relay device includes a bit width distortion correction circuit and a ringing pulse absorption circuit, corrects bit width distortion in bit units using the bit width distortion correction circuit and absorbs and eliminates ringing pulses in a terminus of a communication frame using the ringing pulse absorption circuit.

Claims

1. A relay device for receiving an input signal, and processing the input signal to transmit an output signal,

the relay device comprising:

a bit width distortion correction portion subjecting the input signal to bit width distortion correction for each bit unit,

a ringing pulse eliminating portion subjecting the signal corrected in the bit width distortion portion to ringing pulse of a terminus of the input signal elimination.

2. The relay device according to claim 1, wherein the input signal comprises a signal indicating a head of data,

the bit width distortion correction portion detects the signal indicating the head of the data, and generates a sampling signal to sample the input data of the input signal in bit units according to the signal indicating the head of the detected data as a reference.

3. The relay device according to claim 2, wherein the bit width distortion correction portion samples at the center of 1 bit duration of the input signal.

4. The relay device according to any one of claim 1, wherein the input signal comprises a signal indicating a terminus of data, and

wherein the ringing pulse eliminating portion fixes a signal level of signals continued to the signal indicating the terminus of the data to a predetermined level, when the ringing pulse eliminating portion detects the signal indicating the terminus of the data.

5. The relay device according to any one of claim 2, wherein the input signal comprises a signal indicating a terminus of data, and

wherein the ringing pulse eliminating portion fixes a signal level of signals continued to the signal indicating the terminus of the data to a predetermined level, when the ringing pulse eliminating portion detects the signal indicating the terminus of the data.

6. The relay device according to any one of claim 3, wherein the input signal comprises a signal indicating a terminus of data, and

wherein the ringing pulse eliminating portion fixes a signal level of signals continued to the signal indicating the terminus of the data to a predetermined level, when the ringing pulse eliminating portion detects the signal indicating the terminus of the data.

7. A connector comprising:

a connection portion with a mating connector, wherein a relay device according to any one of claim 1 is provided.

8. A connector comprising:

a connection portion with a mating connector, wherein a relay device according to any one of claim 2 is provided.

9. A connector comprising:

a connection portion with a mating connector, wherein a relay device according to any one of claim 3 is provided.

10. A connector comprising:

a connection portion with a mating connector, wherein a relay device according to any one of claim 4 is provided.

11. A connector comprising:

a connection portion with a mating connector, wherein a relay device according to any one of claim 5 is provided.

12. A connector comprising:

a connection portion with a mating connector, wherein a relay device according to any one of claim 6 is provided.
