SI5344D-D06541-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5344D-D06541-GMR is a jitter attenuator and clock multiplier from Skyworks Solutions, utilizing fourth-generation DSPLL and MultiSynth technologies. It features four inputs and four outputs in a 44-QFN package. The device generates any combination of output frequencies ranging from 100 Hz to 350 MHz from any input frequency. Key electrical parameters include an ultra-low jitter performance of 90 fs rms, a differential input frequency range of 8 kHz to 750 MHz, and LVCMOS input support up to 250 MHz. It operates on a core voltage (VDD) of 1.8 V ±5% and supports independent output supply voltages of 3.3 V, 2.5 V, or 1.8 V.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the numerical suffix D06541, as this part number represents a custom device with a unique frequency plan assigned by Skyworks. Confirm that the tape and reel packaging option aligns with assembly requirements. Ensure compatibility with the ClockBuilder Pro software version used for initial configuration generation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the Si5344D variant when the application requires output frequencies limited to a maximum of 350 MHz. This model provides four inputs and four outputs within a compact 44-QFN package. Verify that the required jitter attenuation bandwidth and holdover stability meet the system specifications before choosing this over higher-frequency variants like the Si5344A.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D family of jitter attenuators. The Si5344 sub-series specifically offers four inputs and four outputs, distinguishing it from the ten-output Si5345 and two-output Si5342 models. All share the same underlying DSPLL and MultiSynth architecture but differ in pin count and output capacity.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5344D-D-GM is the standard commercial equivalent without the custom preprogramming suffix. Si5344B-D-GM serves as a functional alternative if the lower 350 MHz limit is acceptable but different factory programming is desired.
