General Description
The DS1081L is a spread-spectrum clock modulator IC
that reduces EMI in high clock-frequency-based, digital
electronic equipment.
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 three-stated.
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.
The DS1081L is provided in an 8-pin TSSOP package
and operates over a full automotive temperature range
of -40°C to +125°C.
