Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific ordering suffix GM1 corresponds to the 32-pin QFN package supporting up to six outputs. Confirm the NVM code matches the required frequency plan, as custom part numbers are factory-programmed. 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 this component if the application requires up to six independent clock outputs with mixed voltage domains. The 32-QFN package is suitable for space-constrained designs. Verify input source compatibility, as the device supports both external crystals (16–50 MHz) and external clock inputs (10–250 MHz). Consider the need for spread spectrum modulation to reduce EMI in high-speed digital systems.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5332 family of any-frequency clock generators. The 'A' designation indicates support for integer and fractional synthesis modes with external crystal or clock inputs. The 'GM1' suffix specifies the 32-pin QFN package variant, which provides up to six differential outputs. This family is designed to replace multiple discrete oscillators and clock buffers in complex timing architectures.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Replacement should involve verifying pinout compatibility and electrical specifications against other Si5332 variants or equivalent clock generators from the same manufacturer.
