SI5344A-B03540-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344A-B03540-GMR is a factory preprogrammed clock synthesizer and jitter attenuator from the Si5344 family. It features four inputs and four outputs, supporting integer and fractional frequency synthesis with output frequencies up to 1028 MHz. The device utilizes fourth-generation DSPLL technology to achieve ultra-low jitter performance of 90 fs rms. It operates on a 1.8 V core voltage and 3.3 V analog supply, housed in a 44-QFN package measuring 7x7 mm. The unit supports differential and LVCMOS input/output formats within specified frequency ranges.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B03540 suffix against the target design requirements before procurement. Confirm that the standard 44-QFN 7x7 mm package dimensions align with the PCB land pattern. Ensure the serial interface protocol matches the system controller capabilities.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an integrated solution for low-jitter clock generation is required for high-speed networking or telecom applications. The Si5344A variant specifically supports output frequencies up to 1028 MHz, distinguishing it from lower-frequency variants. Use ClockBuilder Pro software to validate the preprogrammed settings if modifications are needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D family of jitter attenuators. The Si5344A variant provides four inputs and four outputs, offering a balance between channel count and form factor compared to the ten-output Si5345. The 'GMR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly processes.
