Note 4-10

This number includes the pad, the bond wire and the lead frame. Printed Circuit Board (PCB)

capacitance is not included in this value. The PCB capacitance value and the capacitance value of

the XO and REFCLK pins are required to accurately calculate the value of the two external load

capacitors.
