SI5332AC08814-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC08814-GM1 is a low-jitter, 6-output programmable clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any combination of output frequencies with excellent jitter performance (190 fs rms). The device supports integer and fractional synthesis modes for external crystal or clock inputs. It features user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS. The component operates within a temperature range of –40 to +85 °C and is housed in a 32-pin QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08814' corresponds to the required frequency plan and configuration. This part number indicates a factory-programmed device assigned via ClockBuilder Pro software. Confirm package type GM1 matches the 32-QFN requirement for your PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model if six differential or single-ended outputs are required. Ensure the design accommodates an external 16–50 MHz crystal or an external clock source, as this variant does not include an embedded crystal. Verify that the target application requires the specific jitter performance and voltage levels supported by the Si5332A grade.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' suffix denotes support for output frequencies up to 333.33 MHz with integer and fractional synthesis modes. The 'GM1' suffix specifies the 32-pin QFN package supporting up to six outputs. The 'R' suffix typically indicates tape and reel packaging, though verification of the specific ordering suffix is recommended.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5332A variants with different output counts (e.g., Si5332ACxxxxx-GM2 for 8 outputs or Si5332ACxxxxx-GM3 for 12 outputs), provided the pinout and package dimensions are compatible with the existing design.
