SI5350A-B03204-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B03204-GTR is a factory-programmed CMOS clock generator manufactured by 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 on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V for both core and output buffers. It features low output period jitter typically below 70 ps pp and supports configurable spread spectrum modulation. The component is housed in a 10-MSOP package providing three LVCMOS outputs.

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 to reduce electromagnetic interference
• Integrated internal load capacitors eliminate external crystal components

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV and Blu-ray player systems
• Set-top boxes and residential gateways
• Audio/video equipment and gaming consoles
• Printers, scanners, and projectors
• Servers and storage networking devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B03204 suffix using ClockBuilder Pro software. Confirm that the 10-MSOP package meets the required footprint constraints. Ensure the target application utilizes a 25 MHz or 27 MHz crystal as the reference input source.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, custom frequency plan is required without I2C reconfiguration capabilities. Choose the 10-MSOP variant if only three output clocks are necessary. Verify that the system design accommodates the pin-controlled spread spectrum and frequency select options provided by the P0-P4 pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of factory-programmable clock generators. Unlike the Si5351 series which supports I2C programming, the Si5350A relies on pre-loaded configurations. It serves as a direct replacement for multiple discrete crystals and oscillators in cost-sensitive designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants with different output counts such as the 16-QFN or 20-QFN packages. Cross-family substitution with Si5351 devices requires I2C interface support and may necessitate firmware adjustments.
