Peak EMI Reducing
Solution
Description
The ASM3P2107A is a versatile spread spectrum frequency
modulator designed specifically for input clock frequencies from
12 MHz to 22 MHz. The ASM3P2107A can generate an EMI reduced
clock from crystal, ceramic resonator, or system clock.
The ASM3P2107A reduces electromagnetic interference (EMI) at
the clock source, allowing system wide reduction of EMI of down
stream clock and data dependent signals. The ASM3P2107A allows
significant system cost savings by reducing the number of circuit
board layers ferrite beads, shielding and other passive components that
are traditionally required to pass EMI regulations.
The ASM3P2107A uses the most efficient and optimized
modulation profile approved by the FCC and is implemented in a
proprietary all digital method.
The ASM3P2107A modulates the output of a single PLL in order to
“spread” the bandwidth of a synthesized clock, and more importantly,
decreases 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 frequency generators.
Lowering EMI by increasing a signal’s bandwidth is called ‘spread
spectrum clock generation.’
Applications
The ASM3P2107A is targeted towards EMI management for high
speed digital applications such as PC peripheral devices, consumer
electronics and embedded controller systems.
