Abstract
System and techniques for selectable clock sources are described herein. An electronic device includes an oscillator for a first clock signal and a tap on an input signal line to a resonator for the oscillator. The tap enables receipt of a second clock signal from an external oscillator. The electronic device includes mode selection circuitry to receives a signal from a tap to an existing input line to the electronic device. The mode selection circuitry uses this signal to select the oscillator output as the clock source or the tap on the input signal line as the clock source.
