SI5332BC09110-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5332BC09110-GM1 is a programmable clock generator utilizing MultiSynth technology to synthesize frequencies with 190 fs RMS jitter. It supports up to six differential outputs in a 32-pin QFN package, enabling integer and fractional synthesis from external crystal or clock inputs. The device features user-configurable output formats including LVDS, LVPECL, HCSL, and LVCMOS, with independent supply voltages for mixed-voltage applications. Operating within a –40 to +85 °C range, it integrates spread spectrum modulation and non-volatile memory for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '09110' corresponds to the required frequency plan and output configuration via ClockBuilder Pro. Confirm that the GM1 suffix matches the 32-pin QFN package requirement for the target PCB layout. Ensure the design accounts for the –40 to +85 °C operating temperature range and RoHS-6 compliance standards.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple oscillators with mixed voltage requirements. The 32-QFN package limits outputs to six differential pairs; verify if higher channel counts are needed. Ensure the input source matches the supported ranges: 16–50 MHz external crystal or 10–250 MHz differential clock. Check compatibility with PCIe Gen1/2/3/4 SRIS specifications if used in such environments.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of any-frequency clock generators. The 'B' designation indicates support for output frequencies up to 200 MHz with integer and fractional synthesis modes. The 'GM1' suffix specifies the 32-pin QFN package supporting up to six outputs. It is factory-programmed with custom configurations assigned by Silicon Labs software.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same package include other Si5332 variants like the Si5332AC or Si5332CC series, provided the frequency range and synthesis mode requirements are met. Verify that substitute parts maintain the same jitter performance and output format capabilities.
