Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08832' corresponds to the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm package type is 40-VFQFN Exposed Pad. Check RoHS-6 compliance status and moisture sensitivity level (MSL 2) requirements for assembly processes. Ensure ClockBuilder Pro software compatibility for any potential reconfiguration needs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when an 8-output clock solution is required with mixed voltage domains. The 'A' grade designation allows for both integer and fractional synthesis modes using external references. Consider the 40-QFN footprint constraints and verify that the embedded crystal option is not needed, as this variant uses external crystals or clocks. Evaluate I2C interface requirements for dynamic configuration if pre-programmed settings are insufficient.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 series, which offers 6, 8, or 12-output configurations. The GM2 suffix specifically identifies the 40-pin QFN package supporting up to 8 outputs. The 'A' in the model number distinguishes it from other grades like 'B', 'C', or 'D' regarding frequency ranges and synthesis modes. It is designed to replace multiple discrete oscillators and clock generators with a single programmable device.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other Si5332 variants with different output counts or packages, such as SI5332AC08832-GM1R (6-output, 32-QFN) or SI5332AC08832-GM3R (12-output, 48-QFN), provided the pinout and output count requirements can be adapted. Verify that the replacement maintains the same NVM configuration or is reprogrammable via ClockBuilder Pro.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the maximum output frequency for differential signals?

The differential output frequency range is 5 to 333.33 MHz.

Can the output signal format be changed dynamically?

Yes, the signal format of each clock output is user-configurable via ClockBuilder Pro or the I2C serial interface to support LVDS, LVPECL, HCSL, or LVCMOS.

Does this device support spread spectrum modulation?

Yes, it supports down and center spread spectrum modulation from –0.1% to –2.5% in 0.01% steps at 30 to 33 kHz to reduce EMI.
