SI5350A-B04206-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B04206-GTR is a factory-programmed 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 single supply voltage of 1.8 V, 2.5 V, or 3.3 V for both core and output buffers. It features low output period jitter typically below 70 ps pp and supports configurable spread spectrum modulation. The component is housed in a 20-QFN package and requires a 25 MHz or 27 MHz crystal reference.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B04206 suffix using ClockBuilder Pro software. Confirm that the required output frequencies and control pin mappings match the system design requirements before procurement. Ensure the ordering suffix corresponds to the correct tape and reel packaging format.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency crystal oscillator replacement is needed for cost-sensitive designs requiring multiple distinct clock rates. Verify that the target application does not require I2C reconfiguration after manufacturing, as this variant is pin-controlled only. Check thermal resistance values against the PCB layout to ensure junction temperature limits are respected.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of clock generators, which are designed to replace discrete crystals and oscillators. The 'A' designation indicates XTAL-only input support, while the 'B' series denotes factory pre-programmed configurations. The GTR suffix specifies the 20-QFN package type with tape and reel delivery.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants with different output counts such as Si5350A-Bxxxxx-GT (10-MSOP) or Si5350A-Bxxxxx-GM1 (16-QFN). Ensure the substitute part number matches the specific frequency plan generated by Skyworks.
