SI5350C-B03196-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03196-GT is a factory-programmable CMOS clock generator with an integrated PLL, manufactured by Skyworks Solutions. It utilizes a dual PLL and MultiSynth fractional divider architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports glitchless frequency changes and configurable spread spectrum. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. This specific part number indicates a factory preprogrammed configuration in a 10-MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory programming data sheet associated with suffix B03196 to confirm the specific output frequencies and pin configurations. Ensure the 10-MSOP package dimensions match the target PCB land pattern. Confirm that the required crystal frequency (25 MHz or 27 MHz) aligns with the programmed reference input settings.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability to reduce system complexity. The 10-MSOP package is suitable for designs requiring three independent clock outputs with limited board space. Verify that the application does not require more than two unique frequencies above 112.5 MHz simultaneously.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350C family, which offers factory-programmable timing solutions. Unlike the Si5351 series, the Si5350C relies on external control pins rather than an I2C interface for configuration. The 'GT' suffix denotes the 10-MSOP package variant, distinguishing it from the 16-QFN and 20-QFN options available in the same product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different package types such as the 16-QFN or 20-QFN versions if pin count requirements change. Cross-family substitution with Si5351A/B/C requires I2C interface support and may necessitate firmware updates.
