onsemi ASM3P2598A
The ASM3P2598A uses the most efficient and optimized modulation profile approved by the FCC and is implemented by using a proprietary all digital method. The ASM3P2598A 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 result in significantly lower system EMI compared to the typical narrow band signal produced by oscillators and most frequency generators.| Part No. | ASM3P2598A |

FEATURES
● Generates a 1X low EMI optimized clock signal at the output.● Integrated loop filter components.
● Operates with a 3.3 / 2.5V Supply.
● Operating current less than 5mA.
● CMOS design.
● Input frequency range: 60MHz to 120MHz for 2.5V 60MHz to 120MHz for 3.3V
● Frequency deviation: ±1.5 (Typ) @ 85MHz Output frequency.
● Available in 6L-TSOP (6L-TSOT-23) Package. Lowering EMI by increasing a signal’s bandwidth is called ‘spread spectrum clock generation.’
APPLICATIONS
The ASM3P2598A is targeted towards all portable devices with very low power requirements like MP3 players, MFP, LCD Panel Module and digital still cameras. ProductDESCRIPTION
The ASM3P2598A is a versatile spread spectrum frequency modulator designed specifically for a wide range of clock frequencies. The ASM3P2598A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals. The ASM3P2598A allows significant system cost savings by reducing the number of circuit board layers, ferrite beads and shielding that are traditionally required to pass EMI regulations.
