SI5350C-B13114-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350C-B13114-GM1 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 16-QFN package variant providing four LVCMOS outputs.

• Features user-configurable control pins for power management and output enable functions
• Provides separate voltage supplies for core logic and output buffers

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV and Blu-ray players
• Set-top boxes and residential gateways
• Servers and storage systems
• Printers and scanners

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the required system timing specifications before integration. Confirm that the 16-QFN package dimensions align with the target PCB land pattern. Ensure the selected crystal frequency (25 MHz or 27 MHz) is compatible with the programmed reference input settings.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a compact solution is needed for generating multiple synchronous and free-running clocks. The 16-QFN package offers four outputs, suitable for designs requiring fewer channels than the 8-output version but more than the 3-output MSOP option. Verify that the application does not require I2C programming capabilities, as this model uses pin-based configuration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of programmable clock generators. It serves as a replacement for discrete crystals, oscillators, and traditional PLL circuits. The 'B' suffix indicates it is factory preprogrammed, distinguishing it from blank devices that require external configuration tools like ClockBuilder Pro.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed variants within the Si5350C family such as SI5350C-Bxxxxx-GT or SI5350C-Bxxxxx-GM, provided the output count and electrical characteristics are compatible.
