SI5344A-B05677-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344A-B05677-GMR is a jitter attenuator and clock multiplier from the Si5344 family, manufactured by Skyworks Solutions. It features four inputs and four outputs housed in a 44-QFN package measuring 7x7 mm. The device supports integer and fractional frequency synthesis with output frequencies ranging from 0.001 MHz to 1028 MHz for differential signals and up to 250 MHz for LVCMOS. It achieves ultra-low jitter of 90 fs rms and operates within a temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and factory preprogramming status. Confirm that the B-series designation aligns with the required frequency range specifications for the target application before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when four independent output clocks are required with high-frequency flexibility up to 1028 MHz. Ensure the design accommodates the 44-QFN 7x7 mm footprint and provides appropriate termination for the chosen output signal formats such as LVDS, LVPECL, or LVCMOS.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344 Rev D series, which combines MultiSynth and DSPLL technologies. It serves as a mid-range option in the family, offering four outputs compared to the ten outputs of the Si5345 and two outputs of the Si5342, all sharing similar core performance characteristics.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements within the same package include other Si5344 variants like the Si5344B-Dxxxxx-GMR, provided the lower frequency limits of the B-series are acceptable for the design requirements.
