SI5350C-B03379-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03379-GT is a factory-programmable CMOS clock generator with an integrated PLL, manufactured by Skyworks Solutions. It utilizes the MultiSynth architecture to generate up to three non-integer-related output frequencies ranging from 2.5 kHz to 200 MHz. The device operates on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V and accepts a crystal reference input at 25 MHz or 27 MHz. It features low output period jitter typically less than 70 ps peak-to-peak and supports configurable spread spectrum modulation for EMI reduction.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple free-running and synchronized clocks using a dual PLL and high-resolution fractional divider architecture.
• Supports glitchless frequency transitions and configurable spread spectrum profiles to minimize electromagnetic interference.
• Provides user-configurable control pins for power down, output enable, frequency select, and loss of lock status monitoring.

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV, DVD/Blu-ray, and set-top box timing
• Audio/video equipment and gaming consoles
• Printers, scanners, and projectors
• Residential gateways and networking communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed frequency configuration against system requirements before procurement. Confirm that the MSOP-10 package variant aligns with the PCB footprint design. Ensure the ordering suffix matches the required tape-and-reel packaging specifications for automated assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a compact solution is needed to replace multiple discrete crystals and oscillators. Verify that the required output count does not exceed three channels. Check if the available programmable control pins satisfy the system's need for dynamic frequency selection or power management features.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of clock generators, which are designed to replace combinations of crystals, oscillators, and PLLs. The 'C' designation indicates support for both crystal and external clock inputs, while the '-GT' suffix specifies the 10-MSOP package type with three outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5350C variants in the MSOP-10 package. Verify that substitute parts maintain identical factory-programmed frequency tables and pinout compatibility to ensure seamless integration without board redesign.
