capacitance (total)

Note 1: 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:

C_XINxC_XOUT

C_L=

C_XIN+ C_XOUT

Then the board trace capacitance between Xin and the crystal should be no more than 2pF. (same is applicable to the

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

C_L=

= 18pF

36pF + 36pF
