SI5345D-B04530-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345D-B04530-GMR is a low-jitter, 10-output clock multiplier and jitter attenuator from Skyworks Solutions. It utilizes fourth-generation DSPLL and MultiSynth technologies to generate any frequency combination from any input source. The device supports differential inputs up to 750 MHz and LVCMOS inputs up to 250 MHz. Output frequencies range from 100 Hz to 350 MHz for differential formats. It operates on a single 1.8 V core supply (VDD) and a 3.3 V analog supply (VDDA). The component is housed in a 64-QFN package measuring 9x9 mm and functions 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 availability status. Factory preprogrammed devices are available with unique numerical sequences assigned by Skyworks. Confirm that the required configuration matches the factory-programmed settings or verify compatibility with ClockBuilder Pro software for custom programming.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when applications require up to ten outputs with frequencies capped at 350 MHz. The Si5345D variant specifically supports integer and fractional synthesis modes within this frequency range. Ensure the design accommodates the 64-QFN package dimensions and provides appropriate thermal management for the specified power dissipation levels under maximum load conditions.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345 family, which includes variants like the Si5345A and Si5345B distinguished primarily by their maximum supported output frequency ranges. The Si5345D is optimized for applications requiring high channel counts but limited to lower output frequencies compared to the 'A' series. All models share the same physical footprint and functional architecture.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5345D variants such as SI5345D-D-GM or SI5345D-Bxxxxx-GMR if different factory configurations are needed. For higher frequency requirements, consider the Si5345A series, though pin compatibility remains consistent across the family.
