Publication number: 20140036988Abstract: Serial data are transmitted between transceivers via a communication path, each bit expressed by a dominant code or a recessive code which vary between dominant and recessive levels, the dominant code having a greater proportion of duration at the dominant level. A device (clock master) can continuously output successive recessive codes to the communication path, in which condition a transceiver can transmit a dominant code by producing an output drive signal which overwrites a part of a recessive code, currently being received from the communication path, to the dominant level. The output drive signal is shaped with a steeper edge slope at a transition from an inactive to an active level than from the active to the inactive level, enabling an increased data transmission rate without increased noise.Type: ApplicationFiled: July 30, 2013Publication date: February 6, 2014Applicant: DENSO CORPORATIONInventors: Hideki Kashima, Tomohisa Kishigami, Naoji Kaneko

Publication number: 20130067129Abstract: In a slave node, a signal processor stores therein wakeup information uniquely defined for the slave node. The signal processor includes a writing unit configured to write the wakeup information into the transceiver at a given timing. A transceiver includes a memory. The wakeup information is written into the memory to be held therein. The transceiver includes a wakeup determiner. The wakeup determiner compares information received via the communication bus with the wakeup information held in the memory if the slave node is operating in the sleep mode, and determines whether the slave node should shift to the wakeup mode according to a result of the comparison.Type: ApplicationFiled: September 12, 2012Publication date: March 14, 2013Applicant: DENSO CORPORATIONInventors: Hideki Kashima, Tomohisa Kishigami

Publication number: 20130034132Abstract: An encoding circuit encodes a NRZ code into a transmission line code. A decoding circuit decodes the transmission line code into a NRZ code. If an operation-mode specified by a setting signal is a normal-mode, a transmission switching circuit provides transmit-data received from an input terminal to the encoding circuit to output the encoded transmit-data as communication-data from a communication terminal. If the operation-mode is a sleep-mode, the transmission switching circuit outputs the transmit-data received from the input terminal as the communication-data from the communication terminal. If the operation-mode specified by the setting signal is a normal-mode, a reception switching circuit provides the communication-data received from the communication terminal to the decoding circuit to output the decoded communication-data as receive-data from an output terminal.Type: ApplicationFiled: August 2, 2012Publication date: February 7, 2013Applicant: DENSO CORPORATIONInventors: Naoji Kaneko, Tomohisa Kishigami, Hideki Kashima

Publication number: 20120314738Abstract: In a transceiver, a clock generator generates a second clock synchronized with a first clock. The second clock has a period corresponding to a duration of one bit of a digital signal. When first transmission data is supplied to the transceiver with being asynchronous to the second clock, a sampling timing generator detects start data of the first transmission data as a start timing, and generates sampling timings based on the first clock in response to the start timing. The sampling timings have intervals each of which is defined to correspond to the period of the second clock. The first sampling timing is spaced from the start timing. A sampling module samples, at each of the sampling timings, the first transmission data, thus generating second transmission data synchronized with the second clock.Type: ApplicationFiled: June 7, 2012Publication date: December 13, 2012Applicant: DENSO CORPORATIONInventors: Hideki Kashima, Tomohisa Kishigami, Naoji Kaneko

Publication number: 20120117287Abstract: In a communication system, a bus allows information to be communicated thereon as signals. Each of the signals has an electrical dominant level thereon and an electrical recessive level thereon. The electrical dominant level is asserted on the bus in priority to the electrical recessive level. Each of a master node and at least one autonomous communicating slave node detects that the bus is in an idle state when the electrical recessive level on the bus is continued for a predetermined period or more, transmits a corresponding header via the bus after detection of the bus being in the idle state, and performs arbitration on the bus based on the corresponding header.Type: ApplicationFiled: November 8, 2011Publication date: May 10, 2012Applicant: DENSO CORPORATIONInventor: Hideki Kashima
