SI5350A-B06299-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B06299-GMR 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 fixed-frequency crystal reference of 25 or 27 MHz and supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. It features separate voltage supply pins for core (VDD) and output buffers (VDDO), supporting levels of 1.8 V, 2.5 V, or 3.3 V independently. The component is available in 10-MSOP, 16-QFN, and 20-QFN packages.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B06299 suffix using ClockBuilder Pro software or official Skyworks documentation. Confirm that the package type matches the required pin count and form factor for the target PCB layout. Ensure the crystal load capacitance requirements align with the internal settings programmed into the device.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing multiple discrete crystals or oscillators to reduce bill of materials cost. Choose the appropriate package variant based on the number of required outputs: 10-MSOP for three outputs, 16-QFN for four outputs, or 20-QFN for eight outputs. Ensure the design accommodates the necessary external crystal components and adheres to the recommended operating temperature range of -40°C to 85°C.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of factory-programmable clock generators. Unlike I2C-programmable variants, the Si5350A series relies on pin-based control logic and pre-loaded configurations. It serves as a direct replacement for standard crystal oscillators in cost-sensitive applications requiring flexible frequency synthesis without the overhead of digital interfaces.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional substitutes within the same family include other Si5350A variants with different output counts or package types, such as Si5350A-Bxxxxx-GT (10-MSOP), Si5350A-Bxxxxx-GM1 (16-QFN), or Si5350A-Bxxxxx-GM (20-QFN). Verify that the replacement part has the identical frequency configuration data loaded at the factory.
