  • Publication number: 20210357353
    Abstract: An on-vehicle system comprises a Clock Extension Peripheral Interface (CXPI) bus and a device coupled to the CXPI bus as a slave node. The device comprises a transceiver configured to: generate a first signal by delaying an inverted signal of a transmission data signal: generate a second signal based on the transmission data signal, where the second signal has a low slew rate: selectively output the first signal or the second signal as a third signal, in response to a selector signal: and generate a clock signal in response to the third signal, where the clock signal is at a high level when the third signal is at a low level, and where the clock signal is at the low level when the third signal is at the high level.

  • Patent number: 10394749
    Abstract: An on-vehicle system comprises a Clock Extension Peripheral Interface (CXPI) bus and a device coupled to the CXPI bus. The device comprises a transceiver configured to: detect a baud rate clock signal and a phase difference between the baud rate clock signal and an input data signal that was generated asynchronously from the baud rate clock signal; obtain a timing from an edge of the baud rate clock signal based the phase difference; capture a value of the input data signal at the timing; and transmit the captured value as an output data signal over the CXPI bus.
