P3PS550AHG-08-CR

Clock Generators, PLLs, Frequency Synthesizers Overview

The P3PS550AHG-08-CR is a high drive, LVCMOS Peak EMI reduction IC designed for spread spectrum frequency modulation. It operates within a supply voltage range of 2.3 V to 3.6 V and supports input/output clock frequencies from 18 MHz to 36 MHz. The device features eight selectable spreading ranges (0.4% to 2.5%) via digital logic inputs SR0, SR1, and SR2. It includes a power-down mode for energy savings and is housed in an 8-pin WDFN package measuring 2 mm x 2 mm.

• Power down control pin for reduced static current consumption

Clock Generators, PLLs, Frequency Synthesizers Applications

• Consumer electronic applications requiring EMI reduction
• Clock source signal conditioning for system-wide EMI mitigation
• Reducing reliance on ferrite beads or shielding in PCB design

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix '08CR' corresponds to the Tape & Reel shipping configuration as specified in the official documentation. Confirm that the component meets Pb-Free, Halogen Free, and RoHS compliance requirements before integration into final assemblies.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when operating clocks between 18 MHz and 36 MHz with LVCMOS compatibility. Ensure the application requires one of the eight specific deviation percentages provided by the SR pins. Verify that the 2.3 V to 3.6 V supply voltage aligns with the target system architecture.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the P3PS550AH series of general-purpose peak EMI reduction ICs manufactured by onsemi. The 'G' indicates lead-free construction, while '08CR' specifies the 8-pin WDFN packaging and reel shipping method. It is distinct from other oscillator types by actively modulating existing clock signals rather than generating them.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 18–36 MHz frequency range, LVCMOS output drive, and 8-pin WDFN footprint. Verify that alternative devices support the same eight discrete spreading range options and operate within the 2.3 V to 3.6 V supply window.
