SI5350C-B02383-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B02383-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 3-output configuration housed in a 10-MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the target design requirements before procurement. Confirm that the 10-MSOP package variant aligns with the PCB footprint constraints. Ensure the specific pinout assignments for the programmable control pins correspond to the system logic levels. Cross-reference the datasheet revision to confirm compatibility with existing reference designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single IC must replace multiple crystals, oscillators, and PLLs to reduce board space and cost. Choose the 10-MSOP version if three outputs are sufficient for the application. Verify that the required output frequencies fall within the 2.5 kHz to 200 MHz range. Consider the separate voltage supply pins if level translation between the core logic and output buffers is necessary.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5350 family of factory-programmable clock generators. It serves as a direct replacement for traditional discrete timing components such as crystal oscillators and standard PLLs.
