SI5332DC08882-GM2

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC08882-GM2 is a factory-programmed, low-jitter clock generator from the Si5332 family. It features an embedded 50 MHz crystal and supports integer-only frequency synthesis with output frequencies up to 200 MHz. The device utilizes MultiSynth technology to achieve phase jitter of 190 fs RMS. It is housed in a 40-pin QFN package (GM2) providing up to eight differential outputs or sixteen LVCMOS outputs. Each output bank supports independent supply voltages of 1.8 V, 2.5 V, or 3.3 V. The component operates within a temperature range of –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Factory-programmed NVM configuration for immediate operation without external programming.
• Embedded 50 MHz reference crystal for free-run mode stability.
• Up to eight differential outputs with user-configurable signal formats (LVDS, LVPECL, HCSL, LVCMOS).
• Independent output supply banks allowing mixed-voltage applications (1.5 V–3.3 V).

Clock Generators, PLLs, Frequency Synthesizers Applications

• Servers and storage systems requiring precise clock distribution.
• Ethernet switches and routers for network synchronization.
• Small cells and mobile backhaul/fronthaul infrastructure.
• Test and measurement equipment.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08882' matches the required frequency plan, as this suffix denotes a unique factory-programmed configuration. Confirm that the GM2 package variant aligns with the PCB footprint requirements. Ensure the host system supports the I2C interface if dynamic reconfiguration or multi-profile switching is needed during operation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when integer-only synthesis is sufficient for the application, as it offers lower complexity than fractional variants. The 40-QFN package provides a balance between output count and board space. Verify that the target output frequencies fall within the 5 MHz to 200 MHz range specified for the 'D' grade silicon revision.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 series of any-frequency clock generators. The 'D' designation indicates integer-mode synthesis capability with a maximum output frequency of 200 MHz. The 'GM2' suffix specifies the 40-pin QFN package supporting up to eight outputs. This distinguishes it from GM1 (6-output) and GM3 (12-output) variants.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical NVM configurations. Generic Si5332 devices must be reprogrammed using ClockBuilder Pro software to match the electrical specifications and pinout. Verify compatibility with existing layout constraints when substituting with other package sizes.
