Product Description

The P2180/81X modulates the output of a single

PLL in order to “spread” the bandwidth of a

synthesized clock, thereby decreasing the peak

amplitudes of its harmonics. This results in

significantly lower system EMI compared to the

typical narrow band signal produced by oscillators

and most clock generators. Lowering EMI by

increasing a signal’s bandwidth is called spread

spectrum clock generation.

The P2180/81X is a versatile spread spectrum

frequency modulator designed specifically for a

wide range of clock frequencies from 20MHz to

40MHz and 60MHz to 160MHz (Refer Input

Frequency and Modulation Rate Table.) The

P2180/81X can generate an EMI reduced clock

form an OSC or a system generated clock. The

P2180/81A

P2180/81D

offer

various

combinations of spread options and percentage

deviations. (Refer Spread Deviation Selections

Table.) These combinations include Down and

Center Spread and percentage deviation range

from ± 0.625% to –3.50%.

The P2180/81X uses the most efficient and

optimized modulation profile approved by the FCC

and is implemented by using a proprietary all-digital

method.

Applications

The

P2180/81X

reduces

electromagnetic

interference (EMI) at the clock source, allowing

system wide reduction of EMI of down stream clock

and data dependent signals. The P2180/81X allows

significant system cost savings by reducing the

number of circuit board layers and shielding that

are traditionally required to pass EMI regulations.

The P2180/81X is targeted towards EMI

management for memory and LVDS interfaces in

mobile graphic chipsets and high-speed digital

applications such as PC peripheral devices,

consumer electronics, and embedded controller

systems.
