Abstract
An interface circuit includes: a connector connectable to a PC; a communication circuit capable of generating a transmission signal to another electronic device; a first region that is set between the connector and the communication circuit to allow an electrical isolation device to be mounted therein; wiring lines used to connect the communication circuit and the connector to each other through the first region; and wiring lines used to connect the electronic circuit and the connector to each other through a region other than the first region.
Claims17
An interface circuit mountable on an electronic device and connectable to another electronic device, the interface circuit comprising:
- a connector connectable to the other electronic device;
- an electronic circuit capable of generating a transmission signal to the other electronic device;
- a first region that is defined between the electronic circuit and the connector to allow an isolation device to be mounted therein;
- a first wiring line to connect the electronic circuit and the connector to each other through the first region;
- and
- a second wiring line to connect the electronic circuit and the connector to each other without passing through the first region.
A substrate to be mounted in an electronic device, on which an interface circuit is mounted, the interface circuit including:
- a connector connectable to another electronic device;
- an electronic circuit capable of generating a transmission signal to the other electronic device;
- a first region that is defined between the electronic circuit and the connector to allow an isolation device to be mounted therein;
- a first wiring line to connect the electronic circuit and the connector to each other through the first region;
- a second wiring line to connect the electronic circuit and the connector to each other without passing through the first region, and a delay compensation circuit to compensate for a delay of a signal transmitted by the interface circuit, the substrate comprising:
- a controller connected to the interface circuit, wherein
- the controller generates an electrical signal for controlling on whether a connection part of the interface circuit should be connected or opened according to a type of a power supply circuit included in the electronic device.
