SI5344B-B05770-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344B-B05770-GM 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 differential output frequencies ranging from 100 Hz to 350 MHz and LVCMOS outputs up to 250 MHz. Input frequency ranges extend from 8 kHz to 750 MHz for differential signals and 8 kHz to 250 MHz for LVCMOS. It achieves an ultra-low jitter performance 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 confirm factory preprogramming details. Confirm package availability and lead times directly with authorized distributors as supply status may vary. Ensure the serial interface requirements match the system design before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when four independent low-jitter outputs are required from multiple input sources. Verify that the target output frequencies fall within the 350 MHz limit defined for the 'B' series variant. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5345/44/42 Rev D family, which utilizes MultiSynth and DSPLL technologies. The Si5344 variant specifically provides four inputs and four outputs, distinguishing it from the ten-output Si5345 and two-output Si5342 models within the same series.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Compatible substitutes include other parts from the Si5344 family such as SI5344A-D-GM or SI5344D-D-GM, provided they meet the specific frequency and jitter requirements.
