SI5350B-B04324-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350B-B04324-GT is a factory-programmable CMOS clock generator with an integrated VCXO, manufactured by Skyworks Solutions. It operates from a fixed-frequency AT-cut crystal reference of 25 or 27 MHz and generates up to eight non-integer-related output frequencies ranging from 2.5 kHz to 200 MHz. The device supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. It features separate core (VDD) and output buffer (VDDO) supply pins for level translation, operating at VDD of 2.5 V or 3.3 V and VDDO of 1.8 V, 2.5 V, or 3.3 V. The specific part number indicates a 3-output configuration in a 10-MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrates a clock generator and VCXO function into a single device to replace multiple crystals and oscillators.
• Generates exact frequency synthesis at each output with zero ppm error using internal PLL or VCXO references.
• Supports user-configurable control pins for output enable, power down, frequency select, and spread spectrum functions.
• Provides highly linear VCXO gain and low output period jitter for precise timing applications.

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV, DVD/Blu-ray, and set-top box systems
• Audio/video equipment and gaming consoles
• Printers, scanners, and projectors
• Handheld instrumentation devices
• Residential gateways and networking communication equipment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B04324 suffix using ClockBuilder Pro software, as this determines the exact output frequencies. Confirm that the 10-MSOP package meets the board space requirements. Ensure the design utilizes a non-pullable AT-cut crystal compatible with the 25 MHz or 27 MHz input specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a combination of free-running and synchronous clocks is required from a single package. The 10-MSOP variant provides three outputs suitable for compact designs. Consider the VCXO functionality if frequency modulation or pull range capabilities are needed for the application timing constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350B family, which combines clock generation with VCXO capabilities. Unlike the Si5350A which lacks VCXO support, the Si5350B allows for synchronous clock generation alongside free-running outputs. The 'B' designation indicates VCXO support, while the suffix defines the factory programming and package type.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5350B-Bxxxxx-GT variants with different frequency plans may serve as functional replacements if the output frequencies match. The Si5350C series offers CLKIN support but lacks VCXO functionality. Verify pin compatibility and voltage levels when substituting with other MultiSynth devices.
