SI5350C-B05497-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B05497-GTR 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 independent core (VDD) and output (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. It operates within an ambient temperature range of -40 °C to 85 °C and features low output period jitter typically below 70 ps peak-to-peak.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B05497 suffix against the target system requirements. Confirm that the 10-MSOP package variant aligns with the printed circuit board land pattern and thermal design constraints. Ensure the selected crystal frequency matches the internal oscillator specifications for optimal performance.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom timing solution requires multiple non-integer-related frequencies without external programmability. Compare the three-output 10-MSOP package against four-output 16-QFN or eight-output 20-QFN variants based on channel count needs. Evaluate the independent VDD and VDDO voltage options to match the logic levels of downstream receivers.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350C family of factory-programmable clock generators. It serves as a replacement for discrete crystals, oscillators, and traditional PLL circuits. The device simplifies board design by consolidating clock generation functions into a single integrated circuit while maintaining low power consumption and small form factor requirements.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different output counts such as the 16-QFN or 20-QFN packages. Non-Skyworks alternatives may require verification of pin compatibility and electrical specifications. Ensure any substitute supports the required frequency range and jitter performance metrics.
