com frequency modulator designed specifically for digital flat panel applications.
The PCS3P2042B reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals.
The PCS3P2042B 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 PCS3P2042B uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method.
The PCS3P2042B 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 PCS3P2042B is targeted towards digital flat panel applications for notebook PCs, palm-s...
