Abstract: An integrated circuit includes a first circuit configured to convert a digital signal of a first format, which includes a sampled version of an analog signal, to a digital signal of a second format. A second circuit is configured to output the digital signal of the second format through a digital interface. An electronic system including a circuit configured to output a digital signal of the analog signal as a bitstream is provided. A clock generator generates a clock for clocking the bitstream. In another aspect, a method for operating an integrated circuit includes converting a digital signal of a first format, which includes a sampled version of an analog signal, to a digital signal of a second format. The digital signal of the second format is outputted through a digital interface. A monitoring or observing device receives directly the digital signal of the second format through the digital interface.

Abstract: An amplitude control circuit includes a pair of peak detectors. The pair of peak detectors are responsive to a voltage reference generator. The amplitude control circuit is configured to be responsive to an oscillating signal of a crystal oscillator and configured to generate a control signal to control an amplitude of the oscillating signal.
