SI5350A-B04223-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B04223-GT is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and high-resolution fractional divider 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
• Independent voltage supplies allow flexible level translation between core and outputs

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
• Residential gateways and networking communication devices
• Servers and storage systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B04223 suffix using ClockBuilder Pro software. Confirm that the 10-MSOP package meets board space requirements. Ensure the external crystal matches the 25 MHz or 27 MHz reference specified in the design. Validate power supply sequencing between VDD and VDDOx pins during integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when replacing discrete crystals or oscillators to reduce bill of materials cost. Choose the 10-MSOP variant if only three output clocks are required. Verify that the target application does not require I2C reconfiguration, as this model uses pin-based control. Check thermal resistance specifications against the expected ambient operating temperature range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators designed for cost-sensitive applications. It serves as a direct replacement for multiple fixed-frequency oscillators. The device simplifies system design by consolidating clock generation functions into a single integrated circuit. It is distinct from the Si5351 series which offers I2C programmability.
