Description

The number of P2008A circuit board layers ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations.

The P2008A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method.

The P2008A 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'.
