Note: The crystal must be such that it oscillates (parallel resonant) at nominal frequency when presented a C Load as specified above.
If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This however may reduce the pull range.
Note that the Cload values above are for the IC only, and do not include PCB parasitics. Crystal specifications for Cload include PCB parasiti cs.
