SI5350A-B05598-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B05598-GT is a factory-programmable 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 fixed-frequency crystal reference of 25 or 27 MHz and supports configurable spread spectrum, glitchless frequency changes, and static phase offsets. It features separate core (VDD) and output (VDDO) supply pins supporting 1.8 V, 2.5 V, or 3.3 V levels. The -GT suffix indicates a 10-MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent frequencies with zero ppm synthesis error
• Configurable spread spectrum for EMI reduction
• Supports glitchless frequency transitions via pin control
• Eliminates need for external power supply filtering due to high PSRR

Clock Generators, PLLs, Frequency Synthesizers Applications

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B05598 suffix using ClockBuilder Pro software before integration. Confirm that the 10-MSOP package meets board space requirements. Ensure the design accommodates the required 25 MHz or 27 MHz crystal load capacitance settings defined in the datasheet.

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 variant if only three output clocks are required. Verify that the target application does not require I2C programming, as this model is configured via control pins.

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 configuration, the Si5350A relies on hardware control pins for feature selection. The -GT designation specifically identifies the 10-MSOP package format within the broader product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants in different packages such as SI5350A-Bxxxxx-GM1 (16-QFN) or SI5350A-Bxxxxx-GM (20-QFN), provided the output count and pinout compatibility are verified.
