The ASM3P2760A is a low-power peak electromagnetic interference (EMI) reducing solution. It generates an EMI optimized clock signal at the output and has integrated loop filter components. The product operates with a 3.3V/2.5V supply and has an operating current less than 4mA. It features a low power CMOS design and an input frequency range of 6MHz to 12MHz for 2.5V and 6MHz to 13MHz for 3.3V. The ASM3P2760A generates a 1X low EMI spread spectrum clock of the input frequency with a frequency deviation of ±0.65% @ 8MHz. It is available in 6 pin TSOT-23, 8 pin SOIC, and 8 pin TSSOP packages.
The ASM3P2760A is a versatile spread spectrum frequency modulator designed to reduce electromagnetic interference (EMI) at the clock source. It operates with 2.5V or 3.3V supplies and consumes less than 4mA of operating current, making it suitable for portable applications like MP3 players and digital still cameras.
The device uses a proprietary all-digital method to modulate the output of a single Phase-Locked Loop (PLL), spreading the bandwidth of synthesized clocks and decreasing peak harmonic amplitudes. It is available in 6-pin TSOT-23, 8-pin SOIC, and 8-pin TSSOP packages.
