Abstract
Disclosed herein is a data receiving circuit including a transmitting section configured to transmit an identifying signal used to identify a state of connection of the data receiving circuit, the identifying signal making potential transitions periodically, in an in-phase signal via a transmission path having AC coupling to a data transmitting circuit for transmitting data in a differential signal via the transmission path.
Claims17
A data receiving circuit, comprising:
- a transmitting section configured to transmit an identifying signal used to identify a state of connection of the data receiving circuit, using an in-phase signal through a transmission path having alternating current coupling, to a data transmitting circuit for transmitting data using a differential signal through the transmission path;
- and
- a clock generating section configured to synchronize a clock generated by the clock generating section with a reference clock signal from the differential signal of the data transmitting circuit;
- wherein the transmitting section transmits a reference clock requesting signal which is identified by the data transmitting circuit as a request to transmit the reference clock signal, where a pulse width of the reference clock requesting signal is different from a pulse width of the identifying signal.
