Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '15710' corresponds to the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm package availability and lead times directly with authorized distributors, as supply status varies by region and time.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SI5332A grade for frequencies up to 333.33 MHz in both integer and fractional modes. Ensure the design accommodates the 32-pin QFN/LGA package constraints. Use ClockBuilder Pro software to define the exact output frequencies and verify that the selected input source (external crystal or clock) matches the application requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'D' indicates the product revision, while 'GM1R' specifies the 32-pin package variant with tape-and-reel packaging. Other variants in the series include GM2 (40-pin) and GM3 (48-pin) packages offering higher output counts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other SI5332A variants with different NVM codes if the frequency plan differs. For pin-compatible alternatives with similar specifications, consider the SI5332B-C-GM1R, noting its lower maximum output frequency limit of 200 MHz.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the maximum output frequency supported by the SI5332A grade?

The SI5332A grade supports differential output frequencies up to 333.33 MHz and LVCMOS outputs up to 170 MHz.

How is the device configured for custom frequency plans?

Configuration is performed using Skyworks' ClockBuilder Pro software, which generates a unique NVM code. Devices with this code are factory-programmed to operate at the specified frequencies without requiring external programming hardware.

Can the output signal format be changed dynamically?

Yes, the output signal format (LVDS, LVPECL, HCSL, or LVCMOS) is user-configurable per output via the I2C interface or during initial setup in ClockBuilder Pro.
