20MHz to 134MHz Spread-Spectrum

Clock Modulator for LCD Panels

DS081L

General Description

Features

The DS1081L is a spread-spectrum clock modulator IC

that reduces EMI in high clock-frequency-based, digital

electronic equipment.

♦ Modulates a 20MHz to 134MHz Clock with Center

Spread-Spectrum Dithering

♦ Selectable Spread-Spectrum Modulation

Using an integrated phase-locked loop (PLL), the

DS1081L accepts an input clock signal in the range of

20MHz to 134MHz and delivers a spread-spectrum mod-

ulated output clock signal. The PLL modulates, or dithers,

the output clock about the center input frequency at a

pin-selectable magnitude and dither rate, allowing direct

EMI control and optimization. In addition, through an

enable pin the dithering can be enabled or disabled for

easy comparison of system performance during EMI test-

ing. This same input pin also allows the DS1081L output

to be tri-stated.

Magnitudes of:

0.5%

1.0%

1.5%

2.0%

♦ Low 75ps Cycle-to-Cycle Jitter

♦ Spread-Spectrum Disable Mode

♦ Pin Compatible with Alliance/PulseCore

Semiconductor P2040 Series Devices

By dithering the system clock, all the address, data,

and timing signals generated from this signal are also

dithered so that the measured EMI at the fundamental

and harmonic frequencies is greatly reduced. This is

accomplished without changing clock rise/fall times or

adding the space, weight, design time, and cost asso-

ciated with mechanical shielding.

♦ Clock Output Disable

♦ Low Cost

♦ Low Power Consumption

♦ 3.3V Single Voltage Supply

♦ -40°C to +125°C Temperature Range

♦ Small 8-Pin TSSOP Package

The DS1081L is provided in an 8-pin TSSOP package

and operates over a full automotive temperature range

of -40°C to +125°C.

Applications

LCD Panels for TVs, Desktop Monitors, and

Notebook and Tablet PCs
