Abstract:
1. An integrated circuit device, comprising: a packaged MEMS-based oscillator circuit configured to support bidirectional frequency margining of a periodic output signal at an output thereof by using a first signal received at a first dual-function input pin thereof to perform a dual-function of (i) disabling/enabling the periodic output signal at the output during a normal mode of operation and (ii) synchronizing changes in a frequency of the periodic output signal during a frequency margining mode of operation; and a second signal received at a second dual-function input pin thereof to: synchronize timing of a transition from the normal mode of operation to the margining mode of operation and, in addition, control whether the changes in the frequency of the periodic output signal during the frequency margining mode of operation are incremental or decremental.
