MPC92469REV 4 JANUARY 23, 2007
Using the On-Board Crystal Oscillator
The MPC92469 features a fully integrated Pierce oscillator
to minimize system implementation costs. The MPC92469
may be operated with a 12 MHz to 20 MHz crystal and without
additional components. Recommended operation for the
crystal should be of a parallel resonant type and a load
specification of CL = 18 pF. See Table 12 for complete crystal
specifications.
If more precise frequency control is desired, the addition of
capacitors from each of the XTAL_IN and XTAL_OUT pins to
ground may be used to trim the frequency as shown in Figure
8.
The crystal and optional trim capacitors should be located
as close to the MPC92469 XTAL_IN and XTAL_OUT pins as
possible to avoid any board level parasitic.
