ASM3P2863AF-06OR

Overview

The ASM3P2863AF-06OR is a spread spectrum clock generator designed to reduce electromagnetic interference (EMI) by modulating the output frequency. It operates with a 12 MHz input and generates a 1X low EMI spread spectrum clock with a typical frequency deviation of ±0.4%. The device supports 2.5V or 3.3V supplies, drawing less than 4mA of operating current. Key electrical parameters include a cycle-to-cycle jitter of ±200ps (typical), an output duty cycle of 45/55%, and rise/fall times under 1.7ns. It utilizes an integrated PLL and loop filter within a compact 6L-TSOP package.

Feature Summary

• Generates a 1X spread spectrum clock from a 12MHz input with ±0.4% typical frequency deviation
• Integrated loop filter components eliminate external filter requirements
• Low power consumption with operating current less than 4mA at 2.5V/3.3V
• CMOS design compatible with standard digital logic interfaces

Applications

• Portable MP3 players
• Notebook computers
• Digital still cameras

Procurement Notes

Verify the ordering suffix 'F-06OR' corresponds to the 6L-TSOP tape and reel packaging configuration. Confirm that the component meets Pb-free specifications as indicated in the datasheet marking guide. Ensure the supply voltage range aligns with the 2.375V to 3.6V operational limits specified for the device.

Selection Notes

Select this component when system-level EMI reduction is required without adding external ferrite beads or shielding. The fixed 12MHz input frequency requirement must be met by the upstream clock source. Verify that the ±0.4% frequency deviation is acceptable for the target synchronous circuits to avoid timing errors.

Part Context

This part belongs to the ASM3P series of peak EMI reducing solutions manufactured by ON Semiconductor. It is functionally similar to other models in the series such as the ASM3P2853A and ASM3P2107A, which also provide spread spectrum clock generation for EMI mitigation in portable electronics.
