    Can you give more information about that board?

    I've never seen a circuit using only one pin for the oscillator (it doesn't mean it doesn't exist).

    EDIT: Interesting, Pierce and Colpitts oscillators have only one output:

    After glancing through that application note, I'd start by checking just how accurate the oscillator is working.
