Low-Power Mobile VGA EMI
Reduction IC
Description
The P1817 is a versatile spread spectrum frequency modulator
designed specifically for input clock frequencies. The P1817 reduces
electromagnetic interference (EMI) at the clock source, allowing
system wide reduction of EMI of down stream clock and data
dependent signals. The P1817 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 P1817 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.’
The P1817 uses the most efficient and optimized modulation profile
approved by the FCC and is implemented in a proprietary all digital
method.
