SI5350C-B02620-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B02620-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 static phase offsets. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. This specific part number corresponds to the 10-MSOP package variant, providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the required system timing specifications before integration. Confirm that the 10-MSOP package dimensions align with the target PCB land pattern. Ensure the selected crystal frequency (25 MHz or 27 MHz) and load capacitance requirements are compatible with the internal oscillator circuitry defined in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability. The 10-MSOP package provides three outputs suitable for simpler designs requiring fewer clock lines. Verify that the required output frequencies fall within the supported range and that the pin-controlled features meet the system's operational needs without dynamic reconfiguration.

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 programming, the Si5350C relies on pin-based control and pre-programmed configurations. The 'B' suffix indicates factory programming, while 'GT' denotes the tape and reel packaging format for the 10-MSOP variant.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different factory configurations but identical packages, such as SI5350C-Bxxxxx-GT. For applications requiring more outputs, consider the 16-QFN or 20-QFN versions. If I2C configurability is needed, the Si5351C series serves as an alternative.
