SI5332DC08825-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC08825-GM1 is a low-jitter, 6-output programmable clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any-frequency integer outputs up to 200 MHz with 0 ppm synthesis error. The device features a 32-pin QFN package and supports user-configurable output signal formats including LVDS, LVPECL, HCSL, and LVCMOS. It operates within a temperature range of –40 to +85 °C and accepts external crystal inputs between 16 and 50 MHz.

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 to 200 MHz.
• Low phase jitter performance of 190 fs RMS when using an external crystal reference.
• Supports spread spectrum modulation for EMI reduction with configurable depth and rate.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Servers and storage systems requiring precise clock distribution.
• Ethernet switches and routers for network infrastructure.
• Small cells and mobile backhaul/fronthaul communication equipment.
• Test and measurement instruments needing stable frequency references.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08825' 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-only synthesis and does not need fractional multi-synth capabilities. Ensure the input reference frequency falls within the 16–50 MHz range for external crystals. Verify that the 6-output count meets system requirements, as other variants offer 8 or 12 outputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of any-frequency clock generators. The 'D' designation indicates it is an integer-mode device with a maximum output frequency of 200 MHz. The 'GM1' suffix specifies the 32-pin QFN package type capable of supporting up to six differential outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same family include other Si5332DC variants with different NVM codes for distinct frequency plans. For applications requiring fractional synthesis, consider Si5332AC or Si5332BC models. Higher output counts are available in the Si5332FD (40-pin) and Si5332GD (48-pin) packages.
