SI5350A-B01997-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5350A-B01997-GM is a factory-programmable CMOS clock generator designed to replace discrete crystals and oscillators. It utilizes a PLL and 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 supports independent core (VDD) and output (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. It features configurable spread spectrum for EMI reduction, glitchless frequency changes, and low period jitter typically under 70 ps pp. Configuration is performed via ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and factory programming details. Ensure the required configuration file matches the exact part number variant. Confirm that the intended application aligns with the supported crystal reference frequencies and output drive requirements specified in the official documentation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a cost-effective solution is needed to replace multiple discrete clock sources. Verify that the required output count fits within the available package options, such as the 10-MSOP for three outputs or the 20-QFN for eight outputs. Ensure the design accommodates the necessary control pins for features like frequency selection or power down if those functions are required by the system architecture.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of programmable clock generators. It is distinct from the I2C-configurable Si5351 series, relying instead on factory programming for its configuration. The device serves as a flexible alternative to fixed-frequency oscillators, allowing designers to customize output frequencies without requiring on-chip programmability interfaces during operation.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed variants within the Si5350A family, such as SI5350A-Bxxxxx-GT or SI5350A-Bxxxxx-GM1, provided the pinout and output count match the specific package requirement.
