SI5350A-B02451-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5350A-B02451-GT is a factory-programmable CMOS clock generator housed in a 10-MSOP package with three outputs. It utilizes a PLL and MultiSynth architecture to generate frequencies from 2.5 kHz to 200 MHz with 0 ppm error using a 25 or 27 MHz crystal reference. The device supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. Core and output supplies operate at 1.8 V, 2.5 V, or 3.3 V independently. Typical power consumption is 25 mA for the core.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates up to eight non-integer-related frequencies with exact synthesis
• Supports glitchless frequency changes via programmable control pins
• Configurable spread spectrum selectable at each output to reduce EMI
• Operates from low-cost fixed-frequency crystals with internal load capacitance

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 communication devices
• Servers and storage systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B02451 suffix against the target system requirements. Confirm that the 10-MSOP package meets the board layout constraints. Ensure the required output frequencies fall within the simultaneous unique frequency limits defined in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when pin-controlled configuration is preferred over I2C programming. Verify that the application requires only three independent clock outputs. Check if the 200 MHz maximum frequency and jitter specifications meet the timing requirements of the downstream logic components.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of factory-programmable clock generators. It differs from the Si5351 series by lacking I2C programmability and VCXO inputs. The -GT suffix indicates tube packaging for the 10-MSOP variant. It serves as a direct replacement for multiple discrete oscillators in cost-sensitive designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5350A-Bxxxxx-GM provides the same functionality in an 8-output MSOP package. Si5351A-Bxxxxx-GT offers identical electrical performance but includes I2C configurability instead of pin control.
