SI5350A-B06183-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B06183-GT is a factory-programmed, user-definable custom clock generator manufactured by Skyworks Solutions. It utilizes a PLL and high-resolution fractional divider 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 glitchless frequency changes. It features configurable spread spectrum for EMI reduction, static phase offset support, and rise/fall time control. Power supply pins allow independent level translation with core VDD and output VDDO supporting 1.8 V, 2.5 V, or 3.3 V.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent, non-integer-related clock frequencies from a single crystal reference.
• Supports glitchless frequency transitions and configurable spread spectrum modulation.
• Features programmable control pins for output enable, power down, and frequency selection.
• Provides separate voltage supply pins for core logic and output buffers to facilitate level translation.

• 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 B06183 suffix using ClockBuilder Pro software. Confirm that the pinout and package type match the design requirements, as the Si5350A family offers varying output counts across different packages. Ensure the external crystal matches the 25 MHz or 27 MHz reference specified 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 based on the required number of outputs and voltage levels. Verify that the application does not require I2C programming, as this variant uses pin-based control. Consider thermal performance if operating at high frequencies or temperatures.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5350A-B06183-GT belongs to the Si5350 family of CMOS clock generators. This family includes variants with different output counts and package types, such as the 10-MSOP (3 outputs), 16-QFN (4 outputs), and 20-QFN (8 outputs). The 'B' series indicates factory pre-programmed configurations, distinguishing it from blank I2C-programmable versions.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other Si5350A variants with matching output counts and package styles, such as SI5350A-Bxxxxx-GT for 3-output MSOP packages. Cross-family replacements like the Si5351 series offer similar functionality but may differ in control interface or input options.
