SI5344B-B04184-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344B-B04184-GM is a jitter attenuator and clock multiplier from the Si5344 Rev D family, manufactured by Skyworks Solutions. It features four inputs and four outputs housed in a 44-QFN package measuring 7x7 mm. The device supports any-frequency synthesis with an output range of 0.001 to 350 MHz. It utilizes fourth-generation DSPLL technology for ultra-low jitter performance of 90 fs rms. The unit operates on a core voltage of 1.8 V ±5% and accepts differential input frequencies from 8 kHz to 750 MHz or LVCMOS inputs from 8 kHz to 250 MHz. It functions within a temperature range of -40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging options and factory preprogramming configurations. Confirm that the B-series designation aligns with the necessary 350 MHz maximum output frequency requirement for the target application design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when applications require low-jitter clock generation up to 350 MHz with flexible input/output configurations. Ensure the system design accommodates the 44-QFN 7x7 mm package dimensions and provides appropriate power supply decoupling for the 1.8 V core and independent output supplies. Utilize ClockBuilder Pro software for optimal configuration of the digital programmable jitter attenuation bandwidth.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344 Rev D series, which combines fourth-generation DSPLL and MultiSynth technologies. It serves as a versatile solution for generating precise clock signals in high-performance networking and telecommunications equipment requiring strict jitter specifications and synchronization compliance.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations
