SI5332DC08818-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC08818-GM1R is a low-jitter, 6-output programmable clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any-frequency outputs up to 200 MHz with integer-only synthesis mode. The device features independent output supply banks (VDDO) supporting 1.8 V, 2.5 V, or 3.3 V levels, enabling mixed-supply applications. It supports user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS. The part is housed in a 32-pin QFN package and operates within a temperature range of –40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08818' corresponds to the required clock configuration, as this suffix denotes a factory-programmed custom part. Confirm the GM1R suffix indicates the 32-pin QFN package with tape-and-reel packaging. Ensure compatibility with the target system's input reference requirements, as this model supports external crystal or clock inputs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a 6-output clock solution with integer-only synthesis is sufficient. The Si5332D variant limits output frequencies to 200 MHz; verify that higher frequencies are not required. Check if the available universal hardware input pins meet control needs such as spread spectrum enable or output enable. Compare against Si5332C if fractional synthesis or higher frequency support is needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of any-frequency clock generators. The 'D' in the part number identifies it as an integer-mode device with a maximum output frequency of 200 MHz. The 'GM1' suffix specifies the 32-QFN package supporting up to six differential outputs. It is designed to replace multiple discrete oscillators and fan-out buffers in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

For direct functional replacement, consider other Si5332D variants with different NVM codes if the clock plan differs. If fractional synthesis or higher frequencies are required, evaluate Si5332C or Si5332A models. For packages with more outputs, compare with Si5332B (40-pin) or Si5332X (48-pin) counterparts.
