SI5345A-D06790-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5345A-D06790-GM is a factory preprogrammed clock synthesizer and jitter attenuator belonging to the Si5345 Rev D family. It features four inputs and ten outputs, supporting integer and fractional frequency synthesis with output frequencies ranging from 0.001 MHz to 1028 MHz. The device utilizes fourth-generation DSPLL technology to achieve ultra-low jitter performance of 90 fs rms. It operates within a temperature range of -40°C to +85°C and is housed in a 64-QFN (9x9 mm) package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific ordering suffix 'D06790' corresponds to the intended factory preprogrammed configuration. This part number format indicates a custom device where the numerical sequence represents the unique preprogrammed settings assigned by Skyworks. Confirm compatibility with the target application's frequency plan before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when an ultra-low jitter solution with multiple differential and single-ended outputs is required. The Si5345A variant supports output frequencies up to 1028 MHz, distinguishing it from lower-frequency variants like the Si5345B. Ensure the design accommodates the 64-QFN package dimensions and thermal requirements for the specified operating temperature range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device is part of the Si5345/44/42 Rev D family, which combines DSPLL and MultiSynth technologies.
