SI5332DC08826-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5332DC08826-GM1 is a 6-output programmable clock generator in a 32-pin QFN package. It utilizes MultiSynth technology to synthesize frequencies up to 250 MHz with 190 fs RMS jitter using an external crystal, or 175 fs RMS with an embedded crystal. The device supports differential outputs (LVDS, LVPECL, HCSL) and LVCMOS formats. Input options include external crystals (16–50 MHz), differential clocks (10–250 MHz), or LVCMOS clocks (10–170 MHz). Output frequencies range from 5 to 333.33 MHz for differential and 5 to 170 MHz for LVCMOS. It features independent output supply pins (VDDO) supporting 1.5 V, 1.8 V, 2.5 V, or 3.3 V.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08826' corresponds to the required frequency plan and configuration via ClockBuilder Pro. Confirm package type is 32-QFN (GM1 suffix). Ensure RoHS-6 compliance requirements are met. Check operating temperature range of -40 to +85 °C against application needs. Validate input source compatibility (crystal vs. clock) for the pre-programmed variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for applications requiring up to six clock outputs with mixed voltage domains. Use when low jitter (<200 fs) is critical. Choose if flexible output formats (LVDS/LVPECL/HCSL/LVCMOS) are needed. Consider if independent VDDO supplies simplify board design compared to fixed-voltage oscillators. Verify input frequency range matches available reference sources.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The GM1 suffix denotes the 32-pin QFN package variant, which supports up to six differential outputs. Other variants include GM2 (40-pin, 8 outputs) and GM3 (48-pin, 12 outputs). The family shares common MultiSynth architecture but differs in pin count and output capacity.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the datasheet. Replacement requires matching output count, jitter performance, and supported signal formats. Verify that alternative devices support the same I2C interface and hardware input configurations if in-system programming is utilized.
