SI5350A-B06401-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B06401-GTR is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. 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 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. The GTR suffix indicates the component is supplied in a tape and reel packaging format.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B06401 suffix using ClockBuilder Pro software before integration. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the selected package type matches the target PCB footprint and thermal management strategy.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a custom frequency plan is required without I2C programming overhead. Verify that the application can accommodate the necessary control pins for power down, output enable, and frequency select functions. Ensure the system design supports the required crystal load capacitance settings via the internal capacitor options.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators, which are designed to replace discrete crystals and oscillators in cost-sensitive applications. The 'A' variant specifically relies on a crystal input, distinguishing it from versions that support voltage-controlled inputs or direct clock signals. The part number structure defines the package type and factory configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants with different package types such as the GM (QFN) or GT (MSOP) suffixes, provided the pinout compatibility is verified. Cross-family substitution with Si5351 models requires careful evaluation of the control interface differences, as Si5351 parts utilize I2C programming rather than pin-based configuration.
