SI5350A-B02720-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B02720-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 features low output period jitter typically below 70 ps pp. It supports configurable spread spectrum, glitchless frequency changes, and static phase offset. Power supply pins allow independent core (VDD) and output (VDDO) voltage selection at 1.8 V, 2.5 V, or 3.3 V.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent clock frequencies from a single crystal reference
• Supports pin-controlled glitchless frequency switching for specific outputs
• Configurable spread spectrum modulation to reduce electromagnetic interference
• Provides separate voltage domains for core logic and output buffers

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B02720 suffix using ClockBuilder Pro software. Confirm that the 10-MSOP package matches the target board footprint. Ensure the required input crystal frequency aligns with the device's 25 MHz or 27 MHz specification before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing discrete crystals or oscillators in cost-sensitive designs requiring multiple clock domains. Choose the 10-MSOP variant if only three outputs are necessary. Verify that the application does not require I2C programmability, as this model relies on factory programming and pin control.

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 reconfiguration, the Si5350A uses direct pin control for features like frequency selection and power down. The -GT suffix indicates the 10-MSOP package containing three clock outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5350A variants with different output counts such as Si5350A-Bxxxxx-GM1 (4 outputs) or Si5350A-Bxxxxx-GM (8 outputs). Cross-family substitution with Si5351A requires adding I2C interface support.
