SI5332AD08983-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AD08983-GM1R is a factory-programmed, low-jitter clock generator from Skyworks Solutions. It utilizes MultiSynth technology to generate any-frequency outputs up to 333.33 MHz with 0 ppm synthesis error. The device supports up to six differential or twelve LVCMOS outputs in a 32-pin QFN package. Key electrical parameters include an RMS jitter of 190 fs for external crystal configurations and 175 fs for embedded crystals. It operates within a temperature range of –40 to +85 °C and accepts input frequencies from 16 to 50 MHz (crystal) or 10 to 250 MHz (clock).

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08983' matches the required clock configuration, as this suffix denotes a factory-programmed unit. Confirm package type is 32-QFN (GM1) and RoHS-6 compliance. Check current availability status as programmable variants may have limited stock compared to blank devices.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, pre-configured clock solution is needed without in-system programming. Ensure the required output count does not exceed six differential or twelve LVCMOS channels. Verify that the target application supports the –40 to +85 °C operating range and compatible input reference sources.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' designation indicates support for integer and fractional synthesis modes with output frequencies up to 333.33 MHz. The 'D' revision specifies product hardware version, while 'GM1R' identifies the 32-pin QFN package with tape-and-reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical NVM programming. Generic Si5332A/B/C/D parts in the same GM1 package can be used if in-system programming via I2C or ClockBuilder Pro Field Programmer is feasible for the application.
