SI5350C-B03304-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03304-GT 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 user-configurable control pins for output enable, power down, and frequency select. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V, accepts 25 MHz or 27 MHz crystals or an external reference clock, and is housed in a 10-MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B03304 suffix against the target system requirements before procurement. Confirm that the 10-MSOP package meets the board layout constraints. Ensure the design accommodates the required crystal frequency and voltage levels specified in the datasheet electrical characteristics.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability to reduce software complexity. The 10-MSOP package limits the device to three outputs; verify if additional channels are needed for the application. Consider the separate VDD and VDDO supply requirements to ensure proper level translation and power sequencing compliance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of factory-programmable clock generators. Unlike the Si5351 series which supports I2C reconfiguration, the Si5350C relies on pin-based control and pre-programmed configurations. The 'B' designation indicates factory programming, while the 'GT' suffix denotes the 10-MSOP package type with tube 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 fixed programming, the Si5351C series serves as a functional alternative within the same product family.
