Patent number: 7936200Abstract: A clock circuit which may include a first clock input for receiving a first clock signal and a second clock input for receiving a second clock signal. A clock calibration unit is connected to the first clock input and the second clock input. The calibration unit may calibrate the second clock signal relative to the first clock signal. The clock calibration unit may have a calibration output for outputting a calibrated clock signal. The clock circuit may include a switch unit connected to the first clock input and the calibration output. The switch unit can select a selected clock signal selected from the first clock signal and the calibrated signal. The switch unit has a switch output for outputting the selected clock signal. A switch control unit is connected to the switch unit for controlling which signal is selected based on a selection criterion and a clock circuit output is connected to the switch unit for outputting the selected clock signal.Type: GrantFiled: January 8, 2007Date of Patent: May 3, 2011Assignee: Freescale Semiconductor, Inc.Inventors: Kamel Abouda, Laurent Guillot

Patent number: 7924061Abstract: A clock failure detection circuit comprises clock failure detection logic having a clock input providing an input clock signal, a counter and a reference clock input providing a reference clock signal to the counter for counting a number of reference clock cycles. The counter comprises a reset input arranged to receive successive reset pulses generated by at least one clock edge of the input clock signal to reset a counter value of the counter. The counter value before reset is used to identify a clock frequency error. A method of detecting a clock failure is also described. By using a counter value based on the reference clock cycles, and a reset trigger based on a clock edge of the input signal, it is possible to identify a clock frequency error in a much shorter time.Type: GrantFiled: March 27, 2006Date of Patent: April 12, 2011Assignee: Freescale Semiconductor, Inc.Inventors: Laurent Guillot, Kamel Abouda, Pierre Turpin
