General Description

The P28XX devices are versatile spread spectrum frequency modulators designed specifically for a wide range of input clock frequencies from 10MHz to 40MHz.

Refer to Input/output Frequency Range Selection Table.

The P28XX can generate an EMI reduced clock from crystal, ceramic resonator, or system clock.

Overview
