Frequency Deviation Selections Table. The P2005A/S
reduces electromagnetic interference (EMI) at the clock
source, allowing system wide reduction of EMI of down
stream clock and data dependent signals. The P2005A/S
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 P2005A/S uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all digital method.
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 P2005A/S is targeted towards EMI management for
high-speed digital applications such as PC peripheral
devices, consumer electronics and embedded controller
systems.
