摘要： An embodiment of a circuit switches between at least a first clock signal and a second clock signal in response to a corresponding switch command, and includes a selection module to select at a switch instant said second clock signal under the control of a signal selector. The circuit comprises a logic-based filter module located downstream of said selection module and configured to produce an outgoing clock signal filtered under the control of a filter signal and also includes a control module configured to receive said switch command and to send said select signal to said selection module delaying said switch instant by a first interval of time, said control module also being configured to send said active filter signal to said filter module in a second interval of time that comprises an edge of the first clock signal and an edge of the second clock signal.

摘要： A circuit switches between at least a first clock signal and a second clock signal belonging to a plurality of clock signals available in an electronic device in response to the corresponding switch command, which comprises a selection module to select at a switch instant said second clock signal in said plurality of clock signals under the control of a signal selector and provide a selected clock signal. According to the invention said circuit comprises a logic-based filter module located downstream of said selection module and configured to produce an outgoing clock signal filtered under the control of a filter signal and also includes a control module configured to receive said switch command and to send said select signal to said selection module delaying said switch instant by a first interval of time, said control module also being configured to send said active filter signal for filtering to said filter module in a second interval of time that comprises an edge of the first clock signal and an edge of the second clock signal that are adjacent to said switching instant.

摘要： A communication system for an HDMI communication interface CEC channel includes a communication module for receiving messages via the CEC channel, a processing unit for processing the received messages and an oscillator for driving the communication module. When the interface is in an active mode, the system is operative to activate the timer upon detection of the start of transmission of a first message, detect the initial bit of the first message, reconstruct and process the first message, and switch the interface from the active mode to standby by deactivating the oscillator. When the interface is in standby, the system is operative to switch the interface to the active condition by activating the oscillator and the timer when the start of a transmission of a second message is detected, detect the initial bit of a transmission of the second message, and reconstruct and process the second message.
