Abstract
A single pin integrated oscillator circuit includes an amplifier having a first input terminal to which an external crystal may be connected, and a second input terminal which receives a feedback path from an output terminal of the amplifier. An oscillator output signal having a relatively large voltage swing is provided from the first input terminal through a buffer. The oscillator operates over a wide range of voltages and process variations, and it can accept an input signal from an external crystal or can accept any clock signal having a swing of approximately 1 V.
