Freescale Semiconductor
MPC92439
As an alternative to parallel resonance mode crystals, the
oscillator also works with crystals specified in the series
resonance mode. With series resonance crystals, the
oscillator frequency and the synthesized output frequency of
the MPC92439 will be a approximately 350-400 ppm higher
than using crystals specified for parallel frequency mode.
This is applicable to applications using the MPC92439 in
sockets designed for the pin and function compatible
MC12439 synthesizer, which has an oscillator using the
crystal in its series resonance mode.Table 13 shows the
recommended specifications for series resonance mode
