The load capacitors added on the board, C1 and C2, should be chosen such that Equation 4 is satisfied (see Table 5-12 for typical values and Table 5-13 for detailed crystal parameter information).
where
Table 5-13 lists part numbers of crystals that have been simulated and confirmed to operate within the specifications in Table 5-12. Other crystals that have nearly identical crystal parameters can be expected to work as well.
In Table 5-13, the crystal parameters labeled C0, C1, and L1 are values that are obtained from the crystal manufacturer. These numbers are usually a result of testing a relevant batch of crystals on a network analyzer. The parameters labeled ESR, DL, and CL are maximum numbers usually available in the data sheet for a crystal.
Table 5-13 also includes three columns of Recommended Component Values. These values apply to system board components. C1 and C2 are the values in picofarads of the load capacitors that should be put on each leg of the crystal pins to ensure oscillation at the correct frequency. Rs is the value in kΩ of a resistor that is placed in series with the crystal between the OSC1 pin and the crystal pin. Rs dissipates some of the power so the Max Dl crystal parameter is not exceeded. Only use the recommended C1, C2, and Rs values with the associated crystal part. The values in the table were used in the simulation to ensure crystal start-up and to determine the worst-case drive level (WC DL). The value in the WC DL column should not be greater than the Max DL crystal parameter. The WC DL value can be used to determine if a crystal with similar parameter values but a lower Max DL value is acceptable.
