ASM3P2775AF-06OR

Overview

The ASM3P2775AF-06OR is a spread spectrum frequency modulator designed to reduce electromagnetic interference (EMI) at clock sources. It operates with a 3.3V supply and accepts input frequencies between 13MHz and 30MHz. The device generates a 1X low EMI spread spectrum clock output with a typical frequency deviation of ±1.8% at 14.7MHz input. Key electrical parameters include a dynamic supply current of 3.5mA, cycle-to-cycle jitter of ±200ps typical, and an output duty cycle of 45/55%. It utilizes an all-digital PLL method to spread bandwidth and decrease harmonic peak amplitudes.

Feature Summary

• Generates EMI optimized 1X spread spectrum clock from 13MHz to 30MHz input
• Integrated loop filter components for simplified design
• Low power consumption with operating current less than 4mA
• Frequency deviation of ±1.8% typical at 14.7MHz input

Applications

• Portable devices with low power requirements
• MP3 players
• Digital still cameras

Procurement Notes

Verify the ordering suffix 'F-06OR' corresponds to the 6L-TSOP package, tape and reel quantity, and lead-free status as specified in the publication order number section. Confirm the temperature range is 0°C to +70°C for this specific variant. Ensure compatibility with the required crystal specifications if using internal oscillator mode.

Selection Notes

Select this component when system-level EMI reduction is required without increasing PCB layer count or adding shielding. It is suitable for applications requiring a single input clock to drive multiple downstream components with reduced spectral peaks. Verify that the input frequency falls within the 13MHz to 30MHz range and that the 3.3V supply voltage is stable.

Part Context

This part belongs to the ASM3P2775A series of peak EMI reducing solutions manufactured by ON Semiconductor. It is functionally equivalent to other variants in the series but differs in packaging and reel configuration. The 'F' indicates lead-free compliance, '06' denotes the 6-pin TSOP package, and 'TR' indicates tape and reel packaging.

Replacement Considerations

Direct replacements include other parts from the ASM3P2775A family such as ASM3P2775AF-08SR, provided the pin count and package type match the board layout. Cross-vendor alternatives must be evaluated for similar modulation profiles, input frequency ranges, and supply voltage requirements.
