SI5335A-B05532-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5335A-B05532-GMR is a web-customizable, any-frequency, any-output quad clock generator and buffer. It synthesizes four non-integer-related frequencies up to 350 MHz using MultiSynth technology, ensuring 0 ppm frequency synthesis error. The device supports three independent pin-selectable configurations and features flexible input references including external crystals (25/27 MHz), CMOS, SSTL/HSTL, and differential inputs. Outputs are configurable as LVPECL, LVDS, CML, HCSL, CMOS, or SSTL/HSTL with independent voltage levels of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply of 1.8, 2.5, or 3.3 V within the -40 to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B05532 via the Skyworks ClockBuilder Pro utility or official datasheet documentation. Confirm that the required pin-selectable modes and output formats match the hardware design requirements before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package with zero ppm error. Ensure the input reference source matches the supported formats (crystal, CMOS, or differential). Verify that the target output voltage levels (1.5V–3.3V) align with the receiving devices' specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5335 family of highly flexible clock generators. The 'A' variant typically denotes specific performance or feature sets within the series, while the suffix indicates a custom factory-programmed configuration. It replaces multiple discrete oscillators and buffers in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-to-pin replacements may exist within the Si5335 family (e.g., other Si5335A/B variants) but require identical configuration programming. Verify electrical compatibility and pinout consistency before substitution.
