SI5350C-B04579-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B04579-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, 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 a 25/27 MHz crystal or a 10–100 MHz external clock. This specific part number indicates a configuration for the 10-MSOP package variant featuring three outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates free-running and synchronized clocks using a dual PLL architecture with high-resolution fractional dividers.
• Provides exact frequency synthesis at each output with zero parts-per-million error.
• Supports user-configurable control pins for output enable, power down, frequency select, and spread spectrum functions.
• Features low output period jitter and HCSL compatible swing capabilities when configured appropriately.

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 factory-programmed timing configuration matches the system requirements before integration. Confirm that the 10-MSOP package dimensions align with the PCB land pattern design. Ensure the selected crystal or reference clock source meets the specified electrical characteristics for optimal performance.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability. The 10-MSOP package is suitable for designs requiring three independent clock outputs with minimal board space. Verify that the required output frequencies fall within the supported range and that the voltage levels match the target application logic.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5350 family of factory-programmable clock generators. It serves as a replacement for multiple discrete crystals, oscillators, and PLLs in compact designs. The 'B' suffix denotes the factory-programmed version, while the 'GT' suffix identifies the 10-MSOP package type with tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different output counts such as the 16-QFN (four outputs) or 20-QFN (eight outputs) packages. For applications requiring I2C configurability instead of factory programming, consider the Si5351 series.
