- L2042A cost savings by reducing the number of circuit board layers ferrite beads, shielding and other passive ponents 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 pared 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’.
FCC approved method of EMI attenuation. Provides up to 15d B of EMI suppression. Generates a low EMI spread spectrum clock of the input frequency. Input frequency range: 30MHz to 75 MHz. Optimized for 32.5MHz, 54MHz, and 65MHz....
