SI5332H-D-GM2

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332H-D-GM2R is an 8-output programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology for integer-only frequency synthesis. It supports output frequencies up to 200 MHz with a low phase jitter of 190 fs RMS when using an external crystal or 175 fs RMS with an embedded 50 MHz crystal. The device operates within a temperature range of –40 to +85 °C and accepts input clocks via external crystals (16–50 MHz), differential clocks (10–250 MHz), or LVCMOS clocks (10–170 MHz). It features user-configurable output formats including LVDS, LVPECL, HCSL, and LVCMOS, powered by independent VDDO supplies.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'GM2R' corresponds to the 40-pin QFN/LGA package in Tape & Reel format. Confirm that the specific NVM code assigned by ClockBuilder Pro matches the required integer-only configuration for the Si5332H grade. Ensure the design accounts for the –40 to +85 °C operating temperature range and RoHS-6 compliance requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SI5332H variant specifically for applications requiring integer-mode synthesis only, as opposed to the fractional-capable Si5332A, C, E, G, or L grades. The GM2 designation indicates an 8-output configuration in a 40-pin package. Verify that the target output frequencies do not exceed 200 MHz, which is the maximum limit for this specific model grade.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'H' suffix denotes the Si5332H grade, which is restricted to integer mode operation with a maximum output frequency of 200 MHz. This distinguishes it from other family members like the Si5332G, which supports fractional synthesis and higher frequencies up to 333.33 MHz.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must be selected from the Si5332 family. Note that upgrading to fractional-capable models (e.g., Si5332G) may require reconfiguration but offers higher frequency support. Downgrading to lower pin-count packages (GM1) reduces output availability. Ensure the replacement maintains the integer-only constraint if system stability relies on it.
