SI5344C-D06599-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344C-D06599-GMR is a factory preprogrammed jitter attenuator and clock multiplier from the Si5344 Rev D family. It features four inputs and four outputs housed in a 44-QFN package. The device generates any combination of output frequencies ranging from 100 Hz to 1028 MHz using integer-only synthesis modes. It supports differential input frequencies up to 750 MHz and LVCMOS inputs up to 250 MHz. Key electrical parameters include an ultra-low jitter performance of 90 fs rms, a core voltage (VDD) of 1.8 V ±5%, and an analog supply (VDDA) of 3.3 V ±5%. The unit operates within a temperature range of –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific suffix 'D06599' corresponds to the intended factory preprogrammed configuration, as this numerical sequence defines the unique internal settings. Confirm the package type matches the design requirements, as standard versions may differ in packaging options such as tape and reel versus tray. Ensure compatibility with the required serial interface protocols and check for any specific environmental compliance certifications relevant to the deployment region.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when integer-only frequency synthesis is sufficient for the application, distinguishing it from fractional variants like the Si5344A. Verify that the output frequency range up to 1028 MHz meets system requirements. Consider the 44-QFN package dimensions for PCB layout constraints. Evaluate the need for factory preprogramming to simplify integration and reduce development time associated with configuring the serial interface and non-volatile memory.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344 Rev D series, which offers four inputs and four outputs in a 7x7 mm 44-QFN package. It utilizes Skyworks’ MultiSynth and DSPLL technologies to provide flexible clock generation. The 'C' designation indicates integer-only synthesis capability, while the 'D' denotes the revision level. The 'GMR' suffix typically implies a tape and reel packaging option, though factory preprogramming overrides standard ordering configurations.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5344A-D-GM provides fractional synthesis capabilities instead of integer-only. Si5344B-D-GM and Si5344D-D-GM are limited to a maximum output frequency of 350 MHz. Si5345C-D-GM offers ten outputs in a larger 64-QFN package. Si5342C-D-GM provides only two outputs in the same 44-QFN form factor.
