SI5332BC09379-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5332BC09379-GM2R is a programmable clock generator in a 40-pin QFN package, supporting up to eight differential outputs. It utilizes MultiSynth technology for any-frequency synthesis with 190 fs RMS jitter using an external crystal. The device accepts input frequencies from 10 to 250 MHz (differential) or 16 to 50 MHz (crystal). Output frequencies range from 5 to 333.33 MHz for differential formats and 5 to 170 MHz for LVCMOS. Each output supports configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS. The core supply voltage is 1.8 V, 2.5 V, or 3.3 V, while output supplies are independently configurable.

• Test and Measurement Equipment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the five-digit NVM code '09379' corresponds to the specific ClockBuilder Pro configuration required for the application. This suffix indicates a factory-programmed device rather than a blank part. Confirm that the GM2R suffix matches the 40-pin QFN package with tape and reel delivery format. Ensure the embedded or external crystal requirement aligns with the BC series specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when eight independent clock outputs are required within a compact footprint. The GM2 designation specifies the 40-pin QFN package. Verify that the target output frequencies fall within the 5–333.33 MHz differential range. Check if the application requires mixed-supply voltage banks, as this device supports independent VDDO settings per bank. Confirm compatibility with the I2C interface for in-system programming if dynamic reconfiguration is needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'B' in the part number typically denotes specific input/output frequency ranges or synthesis modes compared to other letters like A or C. The 'GM2' indicates the 40-pin QFN package variant capable of driving up to eight outputs. The 'R' suffix confirms the tape and reel packaging option for automated assembly.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 40-pin QFN outline and electrical characteristics. Other Si5332 variants with different package sizes (32-pin or 48-pin) are not pin-compatible. Devices from other manufacturers offering similar jitter performance and output counts may require schematic and firmware adjustments due to differences in register maps and control interfaces.
