Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm package type and programming status. The 'GMR' suffix typically indicates a tape-and-reel packaging format, distinct from tray-packaged variants. Confirm that the Rev D designation matches the required silicon revision for your design. Ensure compatibility with ClockBuilder Pro software versions for configuration. Check current availability status as supply constraints may affect lead times.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this device when designing systems requiring ten independent clock outputs with high frequency flexibility. The Si5341B variant supports output frequencies up to 712.5 MHz, suitable for most high-speed digital interfaces. Use ClockBuilder Pro software to optimize divider values for minimal jitter. Consider the integrated NVM feature if in-circuit reprogramming is required. Ensure the application environment stays within the specified operating temperature and voltage ranges.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341/40 Rev D family of clock generators. The Si5341 series offers ten outputs and four inputs, whereas the Si5340 provides four outputs. Both utilize MultiSynth technology for superior jitter performance compared to traditional PLLs. The Rev D iteration includes enhanced features for dynamic frequency changes and improved register map accessibility via I2C/SPI interfaces.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5341B variants with different output frequency limits or packaging options. Verify that substitute parts maintain the same Rev D silicon characteristics. Cross-reference pinouts and electrical specifications to ensure compatibility. Note that base devices require field programming, while preprogrammed parts offer immediate functionality upon installation.
