Spread-system oscillator for auto apps puts the brakes on EMI

Sunnyvale, Calif.&#8212Maxim says its DS1091L is the industry's only 3-volt, all-silicon center-spread clock oscillator for cutting EMI in the automotive temperature range.

The DS1091L is factory-trimmed for use as a stand-alone oscillator from 130 kHz to 66.6 MHz. The center
frequency is accurate to within &plusmn1.75 percent over voltage and temperature.

The company says the DS1091L reduces radiated emissions (RMS voltage) up to 23 dB compared to crystal oscillators. Used as the system clock, the
spread-spectrum DS1091L can simplify, or even
eliminate shielding and filtering. To allow simple
optimization of system design, the DS1091L dither
magnitude (center- or down-dither options) and
dither frequency are pin-selectable. Spread-spectrum modulation can also be disabled.

(1000-up, FOB USA.)
