SI5332H-D-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332H-D-GM1R is a low-jitter, 6-output clock generator from Skyworks Solutions. It utilizes MultiSynth technology to generate any-frequency integer outputs up to 200 MHz with 0 ppm synthesis error. The device features a 32-pin QFN/LGA package and supports user-configurable output formats including LVDS, LVPECL, HCSL, and LVCMOS. It operates within a temperature range of –40 to +85 °C and offers independent supply voltages for output banks.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• MultiSynth technology enables integer frequency synthesis up to 200 MHz with 0 ppm error
• Six differential or twelve LVCMOS outputs with configurable signal formats (LVDS, LVPECL, HCSL, LVCMOS)
• Low phase jitter performance of 190 fs RMS with external crystal input
• Supports independent output supply voltages (VDDO) for mixed-supply applications

Clock Generators, PLLs, Frequency Synthesizers Applications

• Servers and storage systems
• Ethernet switches and routers
• Small cells and mobile backhaul/fronthaul infrastructure
• Print imaging equipment
• Test and measurement instruments

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code assigned by ClockBuilder Pro, as the generic part number requires a unique configuration suffix for factory programming. Confirm the package type matches the design requirements, as the GM1 suffix denotes a 32-pin QFN/LGA footprint. Ensure the embedded or external crystal option aligns with the system's reference clock architecture before ordering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SI5332H variant specifically for integer-only mode operation with output frequencies up to 200 MHz. For fractional synthesis capabilities or higher frequencies up to 333.33 MHz, consider the Si5332A, C, E, G, or L grades. Verify that the required output count does not exceed six differential clocks or twelve LVCMOS signals supported by the 32-pin package.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of programmable clock generators. The 'D' indicates product revision status, while 'GM1' specifies the 32-pin package supporting up to six outputs. The 'R' suffix typically denotes tape and reel packaging for automated assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 32-pin QFN/LGA form factor and support integer-only synthesis if the original application relies on the Si5332H characteristics. Other Si5332 variants like Si5332A or Si5332E offer fractional synthesis but require verification of pin compatibility and software configuration migration.
