SI5350A-B03204-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B03204-GT is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and high-resolution 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 operates on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V for both the core (VDD) and output buffers (VDDO). It features low output period jitter typically less than 70 ps peak-to-peak and supports configurable spread spectrum modulation. The component is housed in a 10-MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent clock frequencies from a single crystal reference without integer relationship constraints

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B03204 suffix using ClockBuilder Pro software or the manufacturer's ordering guide. Confirm that the 10-MSOP package variant meets the required footprint and pinout specifications for the target PCB design before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing discrete crystals and oscillators in cost-sensitive designs requiring multiple distinct clock rates. Ensure the application requires only pin-based configuration rather than I2C programmability. Verify that the required output count does not exceed three, as higher output counts require different package options within the Si5350 family.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350A series, which is distinguished by its pin-programmable interface compared to the I2C-programmable Si5351 series. The 'GT' suffix indicates the 10-MSOP package type with three outputs. It serves as a direct replacement for fixed-frequency crystal oscillators in embedded systems where flexibility in clock generation is needed without complex programming interfaces.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants with different output counts such as the 16-QFN or 20-QFN packages if more outputs are required. For I2C programmability, the Si5351A series offers similar functionality but requires a different configuration method.
