Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'GMR' indicates tape-and-reel packaging versus 'GM' tray packaging when sourcing. Confirm the exact part number against the manufacturer's current datasheet as product lifecycles may change. Ensure compatibility with I2C/SPI programming interfaces if custom configuration is required post-purchase.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when sub-100 fs jitter is critical for system performance. Verify that the required output frequencies fall within the supported range of less than 1028 MHz. Ensure the design accommodates the QFN-44 thermal requirements and the specified operating voltage range of 1.71 V to 3.47 V.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This model belongs to the Si5340 series of any-frequency clock generators. It shares architectural similarities with the Si5341 but offers four outputs instead of ten. The device replaces multiple discrete oscillators and clock buffers, simplifying the clock tree architecture in complex electronic systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5340 variants with different pre-programmed frequencies. For pin-compatible alternatives with different output counts, consider the Si5341 series. Verify that substitute parts support the same output voltage standards and jitter specifications.
