L2042A
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 L2042A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method.
The L2042A 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 a...
