SI5350A-B03183-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B03183-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 25 or 27 MHz crystal reference and supports independent core (VDD) and output (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. It features glitchless frequency changes, configurable spread spectrum, and low period jitter typically under 70 ps pp. The GTR suffix indicates the component is supplied in tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the target design requirements before integration. Confirm that the GTR tape and reel format aligns with automated assembly capabilities. Ensure the specific part number corresponds to the required package type and output count for the intended PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed, pre-configured timing solution is preferred over user-programmable alternatives. Verify that the required output frequencies fall within the 2.5 kHz to 200 MHz range. Check if the available control pins meet system needs for power down or spread spectrum management.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators designed to replace discrete crystals and oscillators. The 'A' variant specifies XTAL-only input capability. The 'B' denotes the specific silicon revision or feature set within the programmable series. It serves as a cost-effective alternative to multiple discrete timing components in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants with different factory programming codes but identical electrical characteristics. Cross-family substitution with Si5351 models requires verification of VCXO or CLKIN support if those inputs are utilized in the original design.
