SI5350A-B06233-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B06233-GT is a factory-programmed CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and MultiSynth architecture to generate up to three 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, static phase offset, and rise/fall time control. Power supply requirements include VDD and VDDO options of 1.8 V, 2.5 V, or 3.3 V. The component is housed in a 10-MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent output frequencies without integer relationship constraints
• Supports pin-controlled glitchless frequency switching between two pre-configured rates
• Integrates selectable spread spectrum modulation for EMI reduction
• Provides user-configurable control pins for power management and output enable functions

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
• Networking and communication infrastructure

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B06233 suffix against the target system requirements using ClockBuilder Pro software. Confirm that the 10-MSOP package dimensions and pinout align with the PCB layout. Ensure the external crystal matches the 25 MHz or 27 MHz specification required by the internal oscillator circuit.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a cost-effective replacement for multiple discrete crystals is needed. The 10-MSOP package limits outputs to three channels; choose larger packages if more outputs are required. Verify that the application does not require I2C programmability, as this variant uses pin-based control logic. Ensure the design accommodates the separate core and output voltage supplies.

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 configuration, the Si5350A relies on hardware pins for control features such as frequency selection and power down states. The 'B' designation indicates a factory-preprogrammed configuration rather than a blank device.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements within the same package include other Si5350A variants with different factory configurations (e.g., SI5350A-Bxxxxx-GT). Cross-family substitution with Si5351 devices requires redesigning the control interface from pins to I2C.
