ASM3P2274AF-06OR

Overview

The ASM3P2274AF-06OR is a Spread Spectrum Frequency Modulator designed to reduce electromagnetic interference (EMI) by generating a 4x spread spectrum clock signal. It operates with a 2.5 V or 3.3 V supply and accepts an input frequency between 12 MHz and 30 MHz. The device produces a 48 MHz to 120 MHz output with a typical frequency deviation of -1.5% at 66 MHz. Key electrical characteristics include a cycle-to-cycle jitter of ±360 ps, a static supply current of 2 µA, and dynamic currents of 3.0 mA at 2.5 V and 4.0 mA at 3.3 V.

Feature Summary

• Generates a 4x EMI optimized clock signal from a single PLL
• Integrated loop filter components for simplified design
• Operates on 2.5 V or 3.3 V CMOS-compatible supply
• Input frequency range of 12 MHz to 30 MHz

Applications

• MP3 players
• Multi-function printers (MFP)
• LCD panel modules
• Digital still cameras

Procurement Notes

Verify the ordering suffix 'F-06OR' corresponds to the TSOP-6 package and tape & reel shipping quantity of 3000 units. Confirm that the component meets RoHS compliance and Pb-Free standards as specified in the datasheet. Ensure the operating temperature range of 0°C to 70°C aligns with system requirements.

Selection Notes

Select this component when EMI reduction is critical for portable devices using clock frequencies between 12 MHz and 30 MHz. The integrated loop filter reduces external component count. Verify that the required output frequency falls within the 48 MHz to 120 MHz range derived from the 4x multiplication factor.

Part Context

This part belongs to the ASM3P2274 family of spread spectrum clock generators. The specific model ASM3P2274AF-06OR denotes the A version variant packaged in a TSOP-6 case 318G-02. It is manufactured by Semiconductor Components Industries, LLC (onsemi).

Replacement Considerations

Consult the manufacturer's documentation for direct substitutes. Generic replacements must match the 4x multiplication ratio, 12-30 MHz input range, and TSOP-6 package dimensions.
