P1727

Notebook LCD Panel EMI

Reduction IC

Features

• FCC approved method of EMI attenuation

system cost savings by reducing the number of circuit

board layers and shielding that are traditionally required

to pass EMI regulations.

• Generates a low EMI spread spectrum of the input

clock frequency

The P1727 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 result 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.

• Optimized for frequency range: P1727X: 20MHz to

40MHz

• Internal loop filter minimizes external components

and board space

• 8 different frequency deviations ranging from

±0.625% to –3.50%

• Low inherent Cycle-to-cycle jitter

• 3.3V Operating Voltage

The P1727 uses the most efficient and optimized

modulation profile approved by the FCC and is

implemented by using a proprietary all-digital method.

• Supports notebook VGA and other LCD timing

controller applications

• Available in 8-pin SOIC.

Applications

The P1727 is targeted towards notebook LCD displays,

other displays using an LVDS interface, PC peripheral

devices and embedded systems.

Product Description

The P1727 is a versatile spread spectrum frequency

modulator designed specifically for a wide range of

clock frequencies. The P1727 reduces electromagnetic

interference (EMI) at the clock source, allowing system

wide reduction of EMI of down stream (clock and data

dependent signals). The P1727 allows significant
