SI5345A-B05764-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345A-B05764-GM is a factory preprogrammed clock synthesizer and jitter cleaner from the Si5345 family. It features four inputs and ten outputs, supporting integer and fractional frequency synthesis with output frequencies ranging from 100 Hz to 1028 MHz for differential signals. The device utilizes fourth-generation DSPLL technology to achieve ultra-low jitter performance of 90 fs rms. It operates within a temperature range of –40 °C to +85 °C and is housed in a 64-QFN package measuring 9×9 mm.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates any combination of output frequencies from any input frequency using integer and fractional synthesis modes.
• Provides ultra-low jitter attenuation of 90 fs rms via fourth-generation DSPLL technology.
• Supports hitless input clock switching between fractionally related inputs and glitchless on-the-fly output frequency changes.
• Includes in-circuit programmable non-volatile memory to ensure known frequency configuration upon power-up.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B05764 suffix against the target design requirements. Confirm that the ordering part number matches the required output frequency plan and voltage levels. Check current availability status as custom preprogrammed devices may have limited stock or longer lead times compared to blank prototypes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed, preconfigured frequency plan is required without field programming. Ensure the application supports the 1028 MHz maximum differential output frequency. Verify that the system environment remains within the specified –40 °C to +85 °C operating temperature range. Confirm compatibility with the 64-QFN 9×9 mm footprint during PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345 Rev D series, which combines MultiSynth and DSPLL technologies. The 'A' designation indicates support for integer and fractional synthesis up to 1028 MHz. The 'B05764' suffix identifies a unique factory preprogrammed configuration generated via ClockBuilder Pro software, distinguishing it from blank prototyping devices.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Blank replacement options include SI5345A-D-GM. Other family members like SI5345B-D-GM offer lower frequency ranges. Verify that any substitute maintains the same pinout and package dimensions if a direct drop-in replacement is necessary.
