SI5332AC08815-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC08815-GM1R is a factory-programmed, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any-frequency outputs up to 333.33 MHz with 0 ppm synthesis error and 190 fs RMS jitter. The device features six differential or twelve LVCMOS outputs in a 32-pin QFN package. It supports external crystal inputs (16–50 MHz) or external clock inputs (LVPECL/LVDS/HCSL/LVCMOS). Output signal formats are user-configurable as LVDS, LVPECL, HCSL, or LVCMOS, with independent supply voltages for output banks.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific five-digit NVM code '08815' matches the required clock tree configuration, as this suffix defines the unique factory-programmed settings. Confirm the 'GM1R' suffix indicates the 32-pin QFN package and tape-and-reel packaging format. Ensure the design accommodates the specified operating temperature range of –40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, pre-validated clock solution is preferred over in-system programming. The 'A' grade supports output frequencies up to 333.33 MHz. Verify that the application requires an external crystal or clock input, as this variant does not include an embedded internal oscillator. Check if the 32-pin form factor meets the board space constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of programmable clock generators. The 'A' designation indicates support for integer and fractional synthesis with output frequencies up to 333.33 MHz. The 'D' revision denotes the product hardware version. The 'GM1' suffix specifies the 32-pin QFN package supporting up to six differential outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 32-QFN package and the specific NVM configuration code. Generic Si5332A devices require reprogramming via ClockBuilder Pro to replicate the SI5332AC08815-GM1R functionality.
