Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix D15698 indicates a factory pre-programmed configuration generated via ClockBuilder Pro software. Confirm that the required serial interface (I2C or SPI) matches your system design if dynamic reconfiguration is needed. Ensure the custom part number aligns with the intended frequency plan and output formats specified in the associated datasheet addendum.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this device when requiring multiple differential and single-ended clock signals from a single component. The Si5341A grade supports fractional synthesis up to 1028 MHz, distinguishing it from integer-only variants. Consider the 64-QFN package dimensions and thermal requirements for PCB layout. Verify compatibility with external crystal specifications if utilizing the internal oscillator between XA/XB pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341/40 Rev D family, which combines a wide-band PLL with proprietary MultiSynth fractional synthesizer technology. The Si5341 variant specifically offers four inputs and ten outputs, designed to replace multiple discrete clock ICs and oscillators. It serves as a versatile platform for synthesizing integer and non-integer related frequencies with zero ppm error.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5341A variants with different suffixes indicating distinct pre-programmed configurations. Devices like the SI5341A-D-GM represent the base model without specific factory programming. Ensure substitute parts maintain the same output count and frequency capabilities if the application requires fixed timing parameters.
