SI5350A-B04499-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B04499-GTR is a factory-programmable CMOS clock generator from Skyworks Solutions. It utilizes a PLL and MultiSynth 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 from a fixed-frequency crystal reference of 25 or 27 MHz. It supports configurable spread spectrum, glitchless frequency changes, and static phase offsets. Supply voltages for the core (VDD) and outputs (VDDO) are independently selectable at 1.8 V, 2.5 V, or 3.3 V. Typical power consumption is 25 mA for the core.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent output frequencies with zero parts-per-million error using high-resolution fractional division.
• Supports user-configurable control pins for output enable, power down, frequency selection, and spread spectrum management.
• Features separate voltage supply domains allowing flexible level translation between core logic and output buffers.
• Includes internal load capacitance options to minimize external component requirements for crystal connections.

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
• Handheld instrumentation devices
• Residential gateways and networking communication equipment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific configuration code 'B04499' against the manufacturer's ClockBuilder Pro database to confirm the exact frequency plan and pin assignments. Ensure the ordering suffix matches the required package type and tape-and-reel specifications. Confirm that the factory-programmed settings align with the target application's timing requirements before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing multiple discrete crystals or oscillators in cost-sensitive designs. Choose the 10-MSOP, 16-QFN, or 20-QFN package based on the required number of outputs. Use ClockBuilder Pro software to define the specific frequency plan and verify that the chosen crystal frequency meets the device's input requirements. Ensure the design accommodates the necessary supply voltage levels for both core and output sections.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of programmable clock generators. It is distinguished by its pin-controlled configuration method, unlike I2C-configured variants in the same family. The 'GTR' suffix indicates it is supplied in a tape and reel format suitable for automated surface-mount assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the Si5350 family require matching the package type and output count. Verify that substitute parts support the same pin-control interface if I2C compatibility is not required. Check that the replacement device supports the specific frequency range and jitter performance needed for the application.
