SI5350C-B13114-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B13114-GM1R 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 with core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V, and accepts reference inputs from 25/27 MHz crystals or external clocks between 10 MHz and 100 MHz.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B13114 suffix against the target system requirements. Confirm that the GM1R package variant matches the PCB land pattern and reflow profile specifications. Ensure the ordering documentation explicitly states the programmed frequencies and control pin settings prior to integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom timing solution requires multiple independent clock frequencies derived from a single reference source. The factory-programmed nature eliminates the need for on-board I2C configuration logic, simplifying the design. Choose this part over programmable variants if the timing parameters are fixed for the production volume.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350C family of clock generators, which offers factory-programmable options for custom timing applications. The Si5350C series complements the Si5351 family by providing pin-controlled configuration capabilities alongside I2C options. It serves as a direct replacement for discrete crystal oscillators and PLL circuits in compact designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different package types such as GT or GM suffixes, provided the pinout compatibility is maintained. Cross-family substitution with Si5351C parts requires verification of the control interface differences, as Si5351C typically relies on I2C rather than pin control.
