发明名称 Clock distribution systems for low power applications
摘要 Integrated circuit devices include first and second periodic signal generators and a power down detection circuit. The first periodic signal generator is configured to generate at least a first periodic signal having a first frequency at an output thereof and the second periodic signal generator is configured to generate a second periodic signal having a second frequency less than the first frequency at an output thereof. The power down detection circuit is configured to selectively provide one or the other of the first and second periodic signals to an output terminal of the integrated circuit device, in response to monitoring a status of a signal received at an input terminal of the integrated circuit device. This received signal reflects a power down status of an external device that receives the selected one of the first and second periodic signals.
