SI5332AC10445-GM2

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5332AC10445-GM2 is a programmable clock generator featuring up to eight differential outputs in a 40-pin QFN package. Utilizing MultiSynth technology, it synthesizes frequencies with 0 ppm error and low jitter (190 fs RMS). It supports integer and fractional modes with input ranges of 16–50 MHz (crystal) or 10–250 MHz (clock). Outputs reach 333.33 MHz differentially or 170 MHz LVCMOS. Configurable formats include LVDS, LVPECL, HCSL, and LVCMOS across independent voltage banks.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '10445' matches the required frequency plan, as this suffix denotes factory-programmed configuration. Confirm the 'GM2' suffix corresponds to the 40-pin QFN package with up to 8 outputs. Ensure ClockBuilder Pro software was used to generate the unique part number during manufacturing.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this device when requiring up to eight synchronized clock outputs from a single source. The GM2 package variant is appropriate for designs needing 8 differential outputs. Verify that the target application frequencies fall within the 5–333.33 MHz range and that the required supply voltages (1.8V, 2.5V, 3.3V) are compatible with the independent VDDO banks.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' grade indicates support for integer and fractional synthesis modes with external crystal inputs. The 'GM2' designation specifies the 40-pin QFN footprint, distinguishing it from the 32-pin (GM1) and 48-pin (GM3) variants which offer fewer or more outputs respectively.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same package require identical output counts and electrical characteristics. Other Si5332 variants (e.g., Si5332BCxxxx-GM2) may serve as substitutes if the frequency range and synthesis mode requirements align with the original design specifications.
