SI5332C-D-GM3

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5332C-D-GM3 is a 12-output programmable clock generator housed in a 48-pin QFN package. It utilizes MultiSynth technology to synthesize frequencies up to 333.33 MHz with 0 ppm error and phase jitter of 190 fs RMS using an external crystal. The device supports independent output supply voltages (1.5 V, 1.8 V, 2.5 V, or 3.3 V) and configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS. It features seven universal hardware input pins, I2C serial interface, and multi-profile configuration support for glitchless frequency changes.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code assigned by ClockBuilder Pro for the desired frequency plan. Confirm that the GM3 suffix corresponds to the 48-pin QFN/LGA package variant. Ensure the design accounts for the –40 to +85 °C operating temperature range and RoHS-6 compliance requirements during component sourcing.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring up to twelve synchronized clock outputs from a single device. The Si5332C grade supports integer and fractional mode synthesis with external crystals. Consider the GM3 package size if board space allows for a 48-pin footprint, which provides the highest output count and flexibility for mixed-supply applications compared to smaller variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5332 family includes variants with 6, 8, or 12 outputs in 32, 40, or 48-pin packages respectively. The 'C' designation indicates support for integer and fractional synthesis modes with external reference inputs. The 'GM3' suffix specifies the 48-pin QFN package option. Other grades like Si5332E offer embedded crystal options, while Si5332A/B/D have different frequency or mode constraints.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same package include other Si5332-GM3 variants such as Si5332A-D-GM3 or Si5332B-D-GM3, provided their specific frequency synthesis modes (integer vs. fractional) and maximum output frequencies align with the system requirements.
