LCD Panel EMI Reduction IC
Description
The ASM3P2182A is a versatile spread spectrum frequency
modulator designed specifically for a wide range of input clock
frequencies from 25 MHz to 210 MHz. (Refer to Input Frequency and
Modulation Rate Table). The ASM3P2182A can generate an EMI
reduced clock from an OSC or a system generated clock. The
ASM3P2182A offers a Center Spread clock and with a percentage
deviation from ± 0.13% or ± 1.24%.
The ASM3P2182A reduces electromagnetic interference (EMI) at
the clock source, allowing system wide reduction of EMI of down
stream clock and data dependent signals. The ASM3P2182A 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 ASM3P2182A uses the most efficient and optimized
modulation profile approved by the FCC and is implemented in a
proprietary all digital method.
The ASM3P2182A 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.’
