The P28xx is targeted towards EMI management for memory interfaces in mobile graphic chipsets and highspeed digital applications such as PC peripheral devices, consumer electronics, and embedded controller systems.
The P28xx is a versatile spread spectrum frequency modulator designed specifically for input clock frequencies from 10 to 40 MHz (see Input/Output Frequency Range Selections). The P28xx can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The P28xx-A and P28xx-B offer various combinations of spread options and percentage deviations (see Output Frequency Deviation and Spread Option Selections section). These combinations include Down Spread, Center Spread and percentage deviation range from ±0.625% to -3.50%.
The P28xx reduces electromagnetic interference (EMI) at the clock source, allowing a system wide EMI reduction for
all the down stream clocks and data dependent signals. The P28xx allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, shielding, and other passive components that are traditionally required to pass EMI regulations.
