Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-configured output frequencies associated with the R0052 custom code before procurement. Confirm that the Industrial temperature rating (–40 °C to +85 °C) aligns with system requirements. Ensure the 6-lead VDFN package dimensions are compatible with the target PCB land pattern design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when dual independent clock signals are required from a single footprint. The ±25 ppm stability specification suits applications demanding precise timing without the reliability risks of mechanical oscillators. Verify that the 2.25 V to 3.6 V supply range matches the system power rails.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the DSC2311 family of configurable MEMS clock generators. The 'I' suffix denotes the Industrial temperature operating range, while '1' indicates ±25 ppm stability. The 'R0052' represents a unique factory-set frequency configuration distinct from standard catalog values.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 6-lead VDFN package and ±25 ppm stability. Other DSC2311 variants with different temperature ranges or stability ratings may fit physically but require verification of environmental and timing specifications.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the function of Pin 1?

Pin 1 is the ENABLE pin. Driving this pin low disables both clock outputs, while floating or connecting it high enables them.

Does the DSC2311 require an external crystal?

No, the device uses internal silicon MEMS technology and does not require an external quartz crystal oscillator.

How many outputs does this device provide?

The DSC2311 provides two simultaneous CMOS clock outputs, designated as CLK0 and CLK1.
