Refer to Input/output Frequency Range Selection Table. The P28XX can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The P28XX-A and the P28XX-B offer various combinations of spread options and percentage deviations. Refer to Frequency Deviation and Spread Selection Table. These combinations include Down and Center Spread, and percentage deviation range from ±0.625% to -3.5%. The P28XX reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of downstream clock and data dependent signals. The P28XX allows significant syst.
