SI5350A-B05934-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B05934-GT is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and high-resolution 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 operates on a single fixed-frequency crystal reference of 25 or 27 MHz. It supports independent core (VDD) and output (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. Key electrical characteristics include typical period jitter below 70 ps pp and low power consumption of approximately 25 mA at the core supply.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent clock frequencies from a single crystal reference
• Supports glitchless frequency changes via programmable control pins
• Configurable spread spectrum functionality for EMI reduction
• Provides user-configurable control pins for output enable, power down, and frequency selection

Clock Generators, PLLs, Frequency Synthesizers Applications

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B05934 suffix using ClockBuilder Pro software. Confirm that the required output count matches the package type, as the GT suffix indicates a 10-MSOP package with three outputs. Ensure the design accommodates the pin-controlled interface rather than I2C programming.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a cost-sensitive application requires replacing multiple discrete crystals and oscillators. Choose the SI5350A variant specifically if pin-control is preferred over I2C configuration. Verify that the required number of outputs does not exceed the three available in the 10-MSOP package; consider other packages for higher output counts.

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 Si5350A relies on pin control for dynamic features. The 'GT' suffix denotes the 10-MSOP package containing three LVCMOS outputs, distinguishing it from the 16-QFN and 20-QFN variants offering four and eight outputs respectively.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5350A-Bxxxxx-GT parts with different factory configurations. For applications requiring more outputs, the Si5350A-Bxxxxx-GM (20-QFN) or GM1 (16-QFN) may be suitable substitutes if pin availability allows.
