This reference may be either an external clock or from a crystal connected between XTAL_IN and XTAL_OUT. The external clock can either be a digital level square wave or sinusoidal and this may be directly coupled to XTAL_IN without the need for additional ponents. If the peaks of the reference clock are below 0 V or above 1.8 V, it must be driven through a DC blocking capacitor (~33p F) connected to...
