A 25MHz, parallel, 18pF load crystal resonator can be used if a crystal source is desired. Table 7-35 shows a typical connection for a crystal resonator circuit. The load capacitor values vary with the crystal vendors; check with the vendor for the recommended loads.
As a starting point for evaluating an oscillator circuit, if the requirements for the crystal are not known, CL1 and CL2 can be set at 27pF, and R1 can be set at 0Ω.
Specification for 25MHz crystal are listed in Table 8-3.
