SI5350C-B02569-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B02569-GTR is a factory-programmable CMOS clock generator 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, configurable spread spectrum, and static phase offsets. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V, accepting reference inputs from 25/27 MHz crystals or 10–100 MHz external clocks. This specific part number indicates a preprogrammed configuration in the 10-MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the B02569 suffix corresponds to the required custom timing configuration, as this variant is factory programmed. Confirm the 10-MSOP package meets board space requirements. Ensure the design supports the specified voltage levels and crystal frequencies. Check for RoHS compliance status if required by local regulations.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed, factory-defined clock solution is preferred over I2C programmable alternatives. The 10-MSOP package provides three outputs suitable for compact designs. Verify that the preprogrammed frequencies meet system requirements, as field reconfiguration is not supported for this ordering suffix.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5350 family of clock generators, which are designed to replace multiple discrete oscillators and PLLs. The 'C' designation indicates support for external clock inputs via the CLKIN pin, while the 'B' suffix denotes factory programming. The '-GTR' suffix typically signifies tape and reel packaging for automated assembly.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different output counts or packages, such as the 16-QFN or 20-QFN versions, provided the custom frequency plan matches. Generic I2C programmable clocks may serve as functional substitutes if firmware can be updated to match the required timing parameters.
