SI5332DC09047-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC09047-GM1 is a low-jitter, 6-output clock generator from the Si5332 family, manufactured by Skyworks Solutions Inc. It utilizes MultiSynth technology to generate any-frequency integer-mode outputs up to 200 MHz with 0 ppm synthesis error. The device features a 32-pin QFN package and supports user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS. It operates within a temperature range of –40 to +85 °C and accepts external crystal or differential/LVCMOS clock inputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Six differential clock outputs with independent voltage supply options (1.5 V, 1.8 V, 2.5 V, or 3.3 V).
• Integer-only frequency synthesis mode supporting output frequencies from 5 MHz to 200 MHz.
• Low phase jitter performance of 190 fs RMS when using an external crystal.
• Supports spread spectrum modulation for EMI reduction with center or down spreading.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Servers, storage systems, and search acceleration hardware.
• Ethernet switches and network routers.
• Small cells and mobile backhaul/fronthaul infrastructure.
• Print imaging equipment and broadcast video systems.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '09047' corresponds to the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm package availability in the 32-QFN format. Check for end-of-life status or obsolescence notices prior to design finalization, as availability may be restricted.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model if the application requires integer-mode synthesis only, as it lacks fractional capabilities found in other Si5332 variants. Ensure the input source matches the supported ranges: external crystals (16–50 MHz), differential clocks (10–250 MHz), or LVCMOS clocks (10–170 MHz). Verify that the 6-output count fits the system requirements to avoid unused pin complexity.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of programmable clock generators. The 'D' in the part number indicates the product revision, while 'GM1' specifies the 32-pin QFN package with six outputs. The '09047' sequence represents a unique non-volatile memory configuration assigned via ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 32-QFN package and 6-output configuration. Other Si5332 variants with different output counts (e.g., GM2 or GM3) are not pin-compatible. Verify that alternative devices support the same integer-only synthesis requirement and input/output voltage levels.
