SI5345A-D06383-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345A-D06383-GM is a factory preprogrammed clock synthesizer and jitter attenuator from the Si5345 family. It features four inputs and ten outputs, supporting differential frequencies up to 1028 MHz and LVCMOS up to 250 MHz. The device utilizes fourth-generation DSPLL technology for ultra-low jitter performance of 90 fs rms. It operates on a core voltage (VDD) of 1.8 V ±5% and an analog supply (VDDA) of 3.3 V ±5%. The component is housed in a 64-QFN package measuring 9x9 mm and supports an operating temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Carrier Ethernet switches
• SONET/SDH line cards

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific numerical sequence '06383' within the part number to confirm the exact factory preprogrammed configuration. This suffix indicates a custom device with fixed settings rather than a blank prototyping unit. Ensure compatibility with the intended frequency plan before procurement, as these parameters cannot be altered post-manufacturing.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a specific, verified frequency configuration is required without in-circuit programming. The 'A' designation confirms support for fractional synthesis and high-frequency outputs up to 1028 MHz. Verify that the application requires the 10-output capability provided by the Si5345 form factor compared to the Si5344 or Si5342 variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345 Rev D family of jitter attenuators. It shares the same physical package and core architecture as other Si5345 models but differs in its internal NVM content. While generic Si5345 devices are programmable via ClockBuilder Pro, this specific part number represents a customized version with a unique preloaded configuration defined by Skyworks.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacement requires another Si5345A-Dxxxxx-GM part with the identical preprogrammed configuration. Generic Si5345A-D-GM units can functionally replace it only if reprogrammed using ClockBuilder Pro software to match the original settings.
