Abstract: Electrostatic discharge protection for high speed transceiver interface is disclosed. In one aspect, an electrical overstress (EOS) protection device includes an anode terminal and a cathode terminal, a silicon controlled rectifier, a second NPN bipolar transistor including a base connected to the anode terminal and an emitter connected to an emitter of the first PNP bipolar transistor, and a second PNP bipolar transistor including an emitter connected to an emitter of the second NPN bipolar transistor and a base connected to a base of the first PNP bipolar transistor. Two or more paths for current conduction are present during a positive overstress transient that increases a voltage of the anode terminal relative to the cathode terminal, including a first path through the silicon controlled rectifier and a second path through the second NPN bipolar transistor and the second PNP bipolar transistor.

Abstract: Determining if a hermetically sealed MEMs device loses hermeticity during operation. In one embodiment, the MEMs device is an accelerometer. A test signal having an associated frequency above an operational frequency range for the accelerometer is provided to the accelerometer at an input during operation of the accelerometer for sensing an acceleration. The output signal of the accelerometer is filtered at least above the operational frequency range of the accelerometer producing a test output signal. The test output signal is then compared to a predetermined threshold to determine if the amplitude of the test output signal differs from the threshold. If the amplitude of the test output signal differs from the predetermined threshold, an error signal is produced indicating that hermeticity of the accelerometer has been lost.

Abstract: A data processing chip with a flexible timing system and method for supplying clocks to a digital data processing system useful for power conservation. A phase locked loop generates a master clock from which a core clock and a system clock are derived. The frequency of each of the core and system clocks is independently controllable relative to the master clock and can be changed on the fly with glitch free and jitter free operation. The data processing chip is well suited for use in hand held electronic devices where power management is a concern. Power can be saved by lowering the frequency of the core clock, even for short intervals of time.

Abstract: An electronic device, such as a microprocessor, with a timing circuit. The timing circuit contains a phase locked loop that, during a first interval, checks whether a control signal in the phase locked loop is between a maximum allowed value and a minimum allowed value. When the control signal in the phase locked loop is above a maximum allowed value or below a minimum allowed value, the control circuit disables the phase locked loop for a second interval. When the control signal in the phase locked loop is below a maximum allowed value and above a minimum allowed value, the timing circuit indicates that the output of the phase locked loop is stable.
