Crystal One. The Crystal One pin is a 25 MHz +/- 30 ppm input signal. It can be
connected to either an oscillator or crystal. If a crystal is used, Crystal Two (XTAL2)
must also be connected.
Crystal Two. Crystal Two is the output of an internal oscillator circuit used to drive a
crystal into oscillation. If an external oscillator is used in the design, XTAL2 must be
disconnected.
Reference. This Reference signal should be connected to VSS through an external
2.49 K Ω resistor.
