- Generates an EMI optimized clock signal at the output. Integrated loop filter ponents. Operates with a 3.3V Supply. Operating current less than 6m A. Low power CMOS design. Input frequency range : 13MHz to 30MHz Generates a 1X and 2X low EMI spread spectrum clock of the input frequency. Output Frequency Selection through FSEL pin Frequency deviation : -1.5% (Typ) @25MHz : -1.5% (Typ) @50MHz Available in 6-pin TSOT-23, 8-pin SOIC and 8-pin TSSOP packages.
The ASM3P2474A uses the most efficient and optimized modulation profile approved by the FCC and is implemented by using a proprietary all digital method. The ASM3P2474A 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...
