SI5345B-B02984-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345B-B02984-GM is a factory preprogrammed clock synthesizer and jitter attenuator from the Si5345 family. It features four inputs and ten outputs, supporting any-frequency generation up to 350 MHz. The device utilizes fourth-generation DSPLL and MultiSynth technologies for ultra-low jitter performance of 90 fs rms. It operates on a 1.8 V core voltage and 3.3 V analog supply, housed in a 64-QFN package with an operating temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Generates any combination of output frequencies from any input frequency using integer and fractional synthesis.
Provides ultra-low jitter attenuation of 90 fs rms with digitally programmable loop bandwidth.
Supports hitless input clock switching, free-run, synchronous, and holdover modes.
Features highly configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific B02984 suffix configuration against the ClockBuilder Pro software or Skyworks documentation to ensure the preprogrammed settings match the design requirements. Confirm package type and temperature grade alignment with system specifications before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when ten differential or single-ended outputs are required with jitter attenuation capabilities up to 350 MHz. Ensure the application supports the 1.8 V core and 3.3 V analog power domains. Verify that the external crystal frequency falls within the recommended 48 MHz to 54 MHz range for optimal jitter performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345 Rev D family, which integrates DSPLL and MultiSynth technologies. The Si5345 variant specifically offers four inputs and ten outputs in a 64-QFN package. The 'B' designation indicates a maximum output frequency limit of 350 MHz, distinguishing it from higher-frequency variants in the same series.
