Note1: For best performance and accurate Center frequencies of this device, It is recommended but not mandatory that  
the chosen crystal meets these specifications  
For maximum accuracy, the total circuit loading capacitance should be equal to CL. This loading capacitance is the  
effective capacitance across the crystal pins and includes the device pin capacitance (CP) in parallel with any circuit  
traces, the clock generator and any onboard discrete load capacitors.  
Budgeting Calculations  
Device pin capacitance: Cxtal = 36pF  
In order to meet the specification for CL = 18pF following the formula:  
Then the board trace capacitance between Xin and the crystal should be no more than 2pF. (same is applicable to the  
CXIN xCXOUT  
CL =  
CXIN + CXOUT  
trace between Xout and the crystal)  
In this case the total capacitance from the crystal to Xin will be 36pF. Similarly the total capacitance between the crystal  
and Xout will be 36pF. Hence using the above formula:  
36pFx36pF  
CL =  
= 18pF  
36pF + 36pF
