SI5345D-B03715-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345D-B03715-GM is a factory preprogrammed, 10-output jitter attenuator and clock multiplier from the Si5345 Rev D family. It supports integer-only frequency synthesis with an output range of 0.001 MHz to 350 MHz. The device features four inputs (differential or LVCMOS) and ten configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL. It operates on a 1.8 V core supply and a 3.3 V I/O supply within a temperature range of –40 °C to +85 °C. The component is housed in a 64-QFN 9×9 mm package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific B03715 suffix against Skyworks documentation to confirm the exact preprogrammed frequency plan. Factory preprogrammed devices are assigned unique numerical sequences representing their configuration. Ensure compatibility with the target system's voltage levels and interface requirements before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when integer-only synthesis is sufficient for the application. The 'D' variant limits the maximum output frequency to 350 MHz, distinguishing it from the 'A' and 'C' variants which support up to 1028 MHz. Verify that the required output frequencies fall within the specified differential and LVCMOS ranges provided in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D series, which integrates DSPLL and MultiSynth technologies. The Si5345 variant specifically provides four inputs and ten outputs in a 64-QFN package. The 'B03715' suffix indicates a custom factory preprogrammed configuration rather than a blank prototyping device.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

SI5345D-D-GM serves as the standard blank replacement for manual programming. For higher frequency requirements up to 1028 MHz, consider the SI5345A-D-GM or SI5345C-D-GM variants. Evaluation boards such as the SI5345-D-EVB are available for development purposes.
